Bruxelles: Mass Moving, 1972. First edition. 4to,  pp,, perfect bound in wraps. Illustrated with b/w reproductions. Text in French.
First and only edition of this compendium of actions and happenings by the Belgian art group, whose public, ludic happenings and installations drew attention to environmental themes. Includes numerous photographs and texts describing such installations as the Hiroshima shadow projects, Ludic City, Ludus Pro Patria, etc. There is virtually no documentation in English on this group, which is a shame, as they are one of the most sustained and provocative art groups of the time. Essential.
Very good with some minor traces of soiling to wraps, and a light crease to the spine. Item #24241
