30 x 21cm, 8pp (self cover). Publisher's catalogue announcing a number of books about Uecker, Goepfert, Schoonhoven and the Zero movement. Large images of works (and of Schoonhoven) in b/w and small images of 7 works internally inlcuding one by Fonatana and another by Piene and texts in German, English and French. Formerly stored in a ring binder so there are two punched holes on the left. Priced thus.
