Slipcase (with label) content of three 3 catalogues and one text work - each uniformly 23 x 17cm. The exhibition (which travelled after starting at the Badischer Kunstverein in Germany in 1980) included reproductions of 'Telephone drawings' by the three artists ie works produced during conversations between the three on the phone (for extra credit: students may compare and contrast these works with Dubuffet who doodled while on the telephone and created his Hourloupe works as a result). The text booklet contains essays on the exhibition. Scarce - all books fine in near fine slipcase. Now scarce despite the 1,000 examples released.
