First edition. 21 x 24 cm, 28 pp. Important SI catalogue of the first and last collective art show of the Situationist International in a gallery. The exhibition aimed to criticize politics as well as the institution of art by creating `an atmosphere of an atomic shelter`. Features an essay by Guy Debord in English, Danish and French. The cover reproduces the poster Danger! Official Secret, by Spies for Peace. Extremely scarce catalogue as most copies were destroyed by the firebombing of J. V. Martin`s appartment where they were stored. Near fine copy with some creasing/dog earring to margins.
