Zurich: Editions Bischofberger, 1972
29.7 x 20.9cm, 8pp plus original card covers. Staple bound. This is the rarest of the Art & Language books published by Bischofberger although in truth the editions were printed in Coventry (without permission) by the university printing section and driven to Zurich by David Rushton in his Morris Minor van. The numbers of each printing are not known but it seems that they varied (Paradigms of Art was published in fewer than 5 copies for example) and there seems to have been relatively few of this book produced despite a claim that there were 200 issued.
This example is in very good condition and is signed in ink by Terry Atkinson.
