next chapter is a typographic-illustrative wall calendar for 2025 that deals with the topic of change. Each month takes up this theme in a different way.

About the designers: Büro KLASS, consisting of Ana Laura Campos Vollmer, Sonja Steven, Sarah Tolpeit, Kerstin Tolpeit & Anna Roidl, is a design studio in Hamburg and Brixen with a focus on typography. The KLASS calendar is now being published for the tenth time, with each calendar having a completely different concept.
Design als Haltung. Handlungsfelder jenseits des Kommerziellen
In recent decades, design has been strongly focussed on stimulating needs and boosting consumption. This concept of design stems from the spirit of the economic miracle and reached its peak in the era of exuberant stock markets and neoliberal economic systems.
Today, we look with horror at the environmental destruction, the division of society and the strengthening of the political right as consequences of this economic system. Time to break new ground! Design and society are closely interrelated. Design influences how people interact with each other and how they behave in the designed environment.
This book paves the way for a new understanding of design that focusses on the process in an open-ended and integrative way, is oriented towards togetherness and does not serve turbo capitalism. Because design can change the world for the better. And because design, understood in this way, gives life more meaning.
Macht Marke. Wie Kreative Zukunft gestalten
The digital transformation poses unprecedented challenges for brand makers and the creatives who accompany them. Excessive demands are becoming the default mode of our time. Certainties waver. Decisions have to be made in the face of great uncertainty.
More than almost anything else, brands are able to become a source of meaning, a binding factor and a shaper of a company. Because people are looking for orientation and meaning. Trust is the currency of our time. Regardless of whether it’s a large corporation or a small business, your own studio or an agency, organization or citizens’ initiative – brand is the compass in confusing times.
Lucas von Gwinner and Dirk von Gehlen provide in Macht Marke. Wie Kreative Zukunft gestalten an introduction to the powerful instrument of the brand that is suitable for everyday use. For creative people who shape the future.
Ich, Wir & Digitalität—Ethik in der Lehre
“I” represents personal reflection, “WE” represents collaboration, and “DIGITALITY” describes the cultural transformation driven by technological innovation.
ICH, WIR & DIGITALITÄT: Ethics in Teaching provides insights into ethical questions from five different perspectives. It can serve as a practical guide with instructions for tasks and learning modules or as a source of inspiration to create spaces for thought, actively engage in social discourses, and help shape the future of education and technology responsibly.

Altari
Enters the rural landscapes of Campania, Italy, where depopulation whispers of a fading past.
In Altari, Paolo Covino presents a photographic topology of bedrooms, each a sanctuary of tradition and heritage. As the elderly cling to their homes, customs, and superstitions, Covino captures the essence of a community in transition. These bedrooms, once revered as places of worship for a fading past, now stand as relics of a bygone era.
Each photograph, documents the intersection of social, cultural, and historical change, where the weight of history threatens to vanish into the ether.
Bury Me in the Back Forty
Bury Me in the Back Forty is the highly anticipated successor to the sold-out books Out West and Crown Ditch by Kyler Zeleny and the final chapter in his prairie trilogy.
For a decade now, Kyler Zeleny has been documenting his hometown, a rural community on the Canadian Prairies with deep Ukrainian roots, consisting of 915 people. Based on the idea that the story of any place evolves over time, Zeleny has been using his own photographs, collected objects, community archives, and hidden histories, to revise the community’s history book from the year 1980.
The result is a pluralistic history of the community that embraces both official and unofficial accounts of events in the community’s past—a community album that contains not only the roses but also the numerous thorns attached to each stem. It encapsulates the collective virtues and vices found at the heart of any complex place on the verge of disappearing. More importantly, it is simply a story being recorded, recollected, and reconfigured—a layered portrait of small town living that is both unique and universal.
The result of which is the stoicism of place, a lived existence, which roars at times and suffers so quietly at others.

FFCGN—Die Macht der Bilder Vol. 4
The colorful, radiant logo of a stylized sun on the cover says it better than words: it’s time to shine. Culture not only fulfills the task of enlightenment, it also offers the opportunity to let our creativity and our hopeful side shine.
And they do: as every year, the brilliant minds of contemporary filmmakers and artists gather at the Film Festival Cologne. They let us dive deep into their craft, their inspirations and the dynamic interplay of storytelling and aesthetics.
The annual publication FFCGN – Die Macht der Bilder Vol. 4 accompanies the festival with many photos, insightful essays and intimate interviews. Through the lens of cinema, the editors provide an insight into the diverse perspectives and innovative approaches that shape today’s cultural landscape and pop culture. Whether the filmmakers are exploring themes such as identity, social justice or the human condition, they illuminate the world with their unique views and perspectives and invite us to accompany them.
Grafikmagazin 05.24 – Haptik & Print
As the name indicates, Grafikmagazin is a print magazine focusing on all things graphic design. Primarily it’s aimed at professional creatives and design students from Germany, Austria, Switzerland, and beyond.
Grafikmagazin presents outstanding work from graphic design, typography, illustration, photography, design theory, research, paper, and printing every two months. The editorial team of Grafikmagazin created a variety of sections and categories but selected focus themes for each issue, like “Illustration”. The topics portray how imaginative, eclectic, and playful graphic design can be while featuring successful branding concepts and niche ideas.
The extensive “Showroom” section lets readers know other creatives and the stories behind design studios worldwide. The “Design and Research” category presents interdisciplinary projects that show how science and research can benefit from creative solutions and play an active role in graphic design. In the “Production and Publishing” section, everything revolves around print. You will find exquisite books, sophisticated annual reports, and high–quality embossed greeting cards. Also, the cover artists of each issue are interviewed or get to highlight their ideas.
Each cover is printed on a different paper, and the design interprets the particular Grafik+ theme more broadly or shares a fresh perspective on a unique design technique. This particular cover was realized in six different versions from different studios and artists, each riso–printed. The Grafikmagazin team, its correspondents, and freelancers are bound and driven by the firm belief that print is not dead. With the will to prove just how alive it is, and the motivation to start something fresh yet deeply traditional, they strive for nothing less than to create another print magazine that makes history.

The Piano
The Piano begins with a loud BANG: piano keys fly around and become the start of something entirely new. Sven Völker views the keys as play materials and continually transforms them into—sometimes very loud and sometimes very quiet—animals.
The Piano playfully encourages children’s creativity and demonstrates how much can come from very little. The style of drawing here reveals the construction of the illustration. The onomatopoeia also creates spaces that can be wonderfully played. Does a dog go “Woof Woof” or “Wau Wau” or … ?
The picture book includes a dictionary that translates English onomatopoeia into German. The funny new vocabulary provides plenty of inspiration to create new sound words.
Emojization. Visual Communication with Emojis
A means of expression for billions of people, emojis have established their function in our everyday lives. Increasingly complex in quality and quantity, these written language companions have long since transcended the realm of written communication to become a pop culture phenomenon of their own. This handbook “Emojization. Visual Communication with Emojis” is a manual and source of inspiration for anyone seeking to understand and use the full potential of emojis in visual communication.
It combines cultural, historical, and theoretical backgrounds with practical application examples. Selected works from recent years demonstrate the formal diversity of emojis and offer inspiration for one’s own work. Specific cases are used to show how emojis can be used in very different ways in the implementation of design tasks and creative projects to thus become part of visual identities.
Alekos Hofstetter – Tannhäuser Tor III
The subject of the Tannhäuser Tor series of works by draftsman and painter Alekos Hofstetter is the relationship between space, time, and distance.
For his creative process, Hofstetter employs changing perspectives on architecture and its history over time. Through his unique power of imagination and sensitivity, Alekos Hofstetter creates a new relationship to the spatial dimensions of existence in his artworks, which are mostly created using mixed media (including ink, colored pencil, and permanent marker) by superimposing iconic, emblematic architectural representations with lettering, elements from comics, and the aesthetics of graphic techniques.
REBEL PRINTS—The Poster Rex Manifesto
Lars Harmsen and Markus Lange, the visionary duo behind Poster Rex, know about the power of signs. Their posters combine contemporary aesthetics with uncomfortable images from our turbulent times, often in a political and/or socio-critical context. Poster Rex represents pop culture and the enduring strength of creativity and human resilience, the rebellious spirit of Poster Rex provokes and awakens hope.
This is evidenced not only by the screen-printed posters but also by the powerful statements of over 25 designers and artists they’ve collaborated and printed with on-site, including notable figures such as Peter Bankov (CZ), Edwin van Gelder (NL), Mirko Borsche (DE), Götz Grämlich (DE), Ariane Spanier (DE), Officina Arara (PT), Yetkin Başarır (TR), and many more …
REBEL PRINTS—The Poster Rex Manifesto is a selection of screen-printed posters created over the last 10 years in collaboration with Poster Rex and artists from around the world.
Unique original screenprints from the Poster Rex sessions will be offered exclusively in the Slanted Shop to accompany the book. More info here.
Jim Avignon: Business as Unusual
The painter, illustrator and conceptual artist Jim Avignon is one of the most unconventional characters in the current German art world. Vibrant colors and unpretentious materials, a good dose of wit and an enormous output are his trademarks.
For the first time an opulent monograph allows a comprehensive insight into the complex oeuvre of the artist, who has always sought confrontation with the establishment and who could never decide whether he wanted to be pop-art, street-art, Picasso on acid or whether he was simply the fastest painter in the world.
Avignon’s narrative about “things not going as planned” is full of concise quips and not without a certain delight. He expounds his peculiar relationship with the art market and describes the exhibitions that finally put him on the map as an exceptional artist. We get to read about odd detours into the world of commerce, a stolen bear, paintings that need ironing, call-for-help socks and how a mural almost landed him in jail. Avignon spills the beans about the high and lows of one of the strangest careers the art world has seen in the last 25 years—expect a lot of detail, an ironic undertone and an abundance of images.
Accompanying texts written by ATAK, Sandra Prill, and Lars Willumeit.
Neoangin
Das musikalische ABC (The musical ABC) is a joint project by Anja Lutz and Jim Avignon created for Typo Berlin 2014.
This synesthetic experiment merges music, illustration and typography in the most entertaining and unorthodox way. Avignon, who is also internationally known as performer Neoangin, has written a song for each letter of the alphabet for which Lutz and Avignon created corresponding visual interpretations on 26 spreads. The musical show has it’ s world premiere at Typo Berlin 2014 and can be followed by leafing through The musical ABC, analogue to the notation of a classical concert (only much more entertaining). The music is also available for online streaming. Enjoy!

Typodarium 2025
Type design is the most subtle instrument of visual communication. Letters, the elementary particles of every design, are primarily decoded in order to capture text. In the face of this serving function, we quickly forget how strongly type design influences the reception of the text. Beyond conscious perception, type interprets the content it contains. Creatives who are aware of this subtle touch in the design process cannot discover enough new typefaces.
Typodarium supports them in this with a daily dose of typography. Every year, Lars Harmsen and Raban Ruddigkeit scout new type designers from all over the world and elicit the latest trends in type design from them. These are then incorporated into the current Typodarium.
It has never been so nice to literally have your eye on the pulse of the times. Breathe the spirit of 2025 into your designs, nonchalant topicality ideally with a never-seen-before bonus …
