					<description><![CDATA[Alba: Laboratorio Sperimentale Del Movimento Internazionale Per Una " Bauhaus Immaginista", 1956

14.5 x 22.8cm, black and green offset letterhead created for the vastly important "First World Congress of Free Artists" which brought together Enrico Baj, Jacques Calonne, Constant, Giuseppe Pinot Gallizio, Asger Jorn, Piero Simondo, Ettore Sottsass Jr, Elena Verrone (from the International Movement for an Imaginist Bauhaus), Gil J. Wolman (from the Lettrist International/Potlatch), Sandro Cherchi, Franco Garelli  , Jan Kotik, Pravoslav Rada (Czechoslovakia), Charles Estienne, and Klaus Fischer to discuss joint projects.

The importance of this meeting cannot be underwritten - it brought together many of the main currents of the European International Avant Garde and laid the foundations for the eventual formation of the International Situationists.

JOINT:

Alba: Laboratorio Sperimentale Del Movimento Internazionale Per Una " Bauhaus Immaginista", 1956

12.3 x 15.5cm, green and black on white printed envelope for the same event.

Price is for both items together - the stationery for a major landmark in European political and art history.

Both VG+ if mildly browned.
