Dieter Roth was a multi-faceted artist, as is shown in this third volume in a series of books featuring works from the Dieter Roth Foundation. He worked in many media and Books + Multiples includes over 200 artist's books, 40 multiples, jewellery, films, videos, tapes, records and posters produced over a 50-year period. Starting with Op Art and visual poetry books, he then experimented with all aspects of offset printing and by the 1990s was producing copy books, using photocopiers. His multiples were equally innovative, incorporating materials such as chocolate, sugar and spices. images and sound remained to the end. The jewellery editions shed light on a little-known aspect of his early work, while the last section of the book shows all his poster designs.
