Custom all-caps typeface in medium weight, used throughout the museum's documents and announcements. The nearby, recently restored Villa Majorelle uses the typeface as well for its signage. The typeface gathers different Art Nouveau forms found in architecture, furniture or art and transposes them into one harmonizing design. It is further is characterized by wide capitals in many variants. The six styles (Crocus, Dahlia, Gingko, Nenuphar, Rose, Thistle) are arranged from the most quiet to the most expressive letter­forms. Designed with Philippe Tytgat. Graphic design by Lab.Leblond.Tytgtat, Nancy. The typeface was later extended to minuscules in diverse weights, and published by Poem as a full retail type family in 2022.

Koch Lichte Grotesk is the newest revival of Lichte Neuland by Rudolf Koch, designed by Edvinas Žukauskas and Jérôme Knebusch and published by Poem for Neuland’s centenary in 2023. Lichte Neuland appeared five years after Neuland in 1928, in the Gebr. Klingspor specimen dedicated to the American market by the Continental Typefounders Association. Koch Lichte Grotesk is an accurate revival of the 12 pt Cicero size, the smallest one. It is currently the only fully identified original size, as shown on the 1928 index card of the German Association of Typefounders. This association was founded at the beginning of the 20th century and most German type foundries were members. It served to represent their interests in economic, political and legal matters. A secondary source are the Lichte Neuland Cicero letters from the letterpress workshop P98A, Berlin. Koch Lichte Grotesk is available in four fonts: 12 Cicero, 12 Cicero Plain, 12 Cicero Inline and 12 Cicero Line. 10% of licence purchases are deposited each year as flowers on Koch's grave.

In 2011, students of ESAL Metz started within a workshop with Argentinian type designer Alejandro Lo Celso and their teacher Jérôme Knebusch a specific design for their school. Looking for a bookish typeface tending to modern forms, the students found interesting references in the work of Baskerville and Didot, precisely: exactly inbetween. The type grew during the following years, each time in intensive workshop sessions, to a complete type family named Messine, covering text, display, poster, italic, bold, sans and serif versions. Today, Messine is the official and exclusive typeface of the school, used all over its documents.

Rudolf Koch and Fritz Kredel's remarkable Blumenbuch [Book of Flowers] was published between 1929 and 1942, from precious volumes and portfolios to pocket editions, involving numerous collaborators, printers and publishers such as Mainzer Presse in Mainz, Ernst-Ludwig-Presse in Darmstadt and Insel-Verlag, Leipzig. The Insel paperback edition continued to be printed throughout the 20th century. Koch began drawing wild flowers in 1922. He explains that he 'collected [the flowers] at random and without any particular purpose. I only drew those that grew in Offenbach and the surrounding area...'. A member of Koch's Werkstatt, the young Kredel, engraved most of the 250 drawings. The flowers were engraved on wood and coloured entirely by hand. The entire project - the various editions, sketchbooks, printing tests and original woodcuts - constitutes an exceptional archive that was exhibited for the first time in France, at the Modulab gallery in Metz The exhibition curated by Jérôme Knebusch is a joint venture between the Klingspor Museum, Poem, Modulab and the École nationale d'art et de design de Nancy.

Instant is an anachronic type family going from thin, quick handwritten letters to stable, black typographic shapes. Each of the five styles correspond to a singular design related to a specific stroke speed and weight: Vivid, Quick, Regular, Slow, Heavy. Hommage to the poet, painter and writer Henri Michaux (1899 – 1984), it questions fundamental differences between handwriting and typography, type family consistency and the relation and usage of roman, bold and cursive faces. Instant was designed by Jérôme Knebusch in 2005 as part of a personal research project at ANRT Nancy. First published in 2012 by BAT Foundry, it is today available at Poem. In 2020, Instant Variable was added to the collection.

Decode Blockdock is a font which integrates a representative, uniformed glyph for each encoded Unicode block. Commissioned by Johannes Bergerhausen from Institut Designlabor Gutenberg/ Hochschule Mainz and used for the decodeunicode and worldswritingsystems websites (links below), and its iconic poster together with the missing scripts (ANRT research program). Ongoing work since 2015.
