Koeln and New York: Verlag Gebr. Koenig, 1970. First edition. Oblong 4to, upaginated. Spiral bound in card covers. Text in German and English.
First edition of one of the most radical works of art and pedagogy of the 1970's, which exemplified the best aspects of the Fluxus tendency. The book solicited the active participation of the reader, or, as the cover text states, "It is a multi-book. The space provided for the reader's use is nearly the same as the author's own."
