One of several caps-only Art Nouveau alphabets drawn by Étienne Mulier and published around 1900 in an album of 28 color lithographs titled Lettres et Enseignes Art Nouveau.
A version “redrawn and completed” by Walter Haettenschweiler and Armin Haab is reproduced in Lettera 3 (1968) as Alphabet Art Nouveau. Obvious differences besides the fact that Mulier’s version is bichromatic can be found in the detailing of some of the tendrils (e.g. ‘D’, ‘M’).
Digitized by Dieter Steffmann as Art Nouveau Caps (1999, with numerals from Arnold Böcklin, used for sample).
