GERSTNER, Karl. Kompendium für Alphabeten. Eine Systematik der Schrift.

(Teufen, Switzerland): Verlag Arthur Niggli, 1972. Hardcover. 15.4 cm by 15.6cm. 180 pages. Gerstner’s influential study of alphabet systems and typographic structure. Gerstner treats typography not as a set of fixed styles but as a rational system governed by proportion, rhythm, contrast, and modular relationships, reflecting his broader commitment to methodical design thinking. Densely illustrated and rigorously organised, the book functions both as a theoretical framework and a practical reference, situating letterforms within a systematic modernist approach to visual communication.  A very good copy in dust jacket.
