Published to accompany this year's exhibition at Martin-Gropius-Bau, Berlin, here is the most comprehensive publication on the ZERO movement, which thrived from 1958 to 1966. It explores the work of the founders Heinz Mack, Otto Piene and Günther Uecker, alongside international artists who were close to ZERO such as Yves Klein and Lucio Fontana, and such lesser-known artists as Hermann Goepfert, Oskar Holweck and Hans Salentin.
