29.5 x 20.5cm, 32pp. Original card covers. Exhibition catalogue with b/w images of works by Boetti, Fabro, Merz and Paolini with texts supplied by the artists. The front cover includes the name of Salvo, although graphically different from the others (colored with the tricolor, while the others are in black), however in the catalog the artist is not included – presumably the colouring of the cover being his contribution to the book. Slight ink mark to cover else VG. Scarce.
