Letterletter was originally a series of 15 issues of a "journal of typographic metaphysics" published sporadically and distributed to a select group who made up the membership of the Association Typographique International (ATypI). It is an iconoclastic collection of essays on typography, writing and life and is the work of the master calligrapher, type designer and teacher Gerrit Noordzij with contributions by Nicolette Gray, Max Caflisch, Fernand Baudin and others. Letterletter is an invaluable design tool and a pleasure to read and reread for all those who care about the written word.
As Robert Bringhurst notes in his introduction, the middle two pages of the first four-page issue of Letterletter held "more information on the structure and nature of letterforms than most professional typographers then working (1970) had ever seen in their lives".
