1997-06

letter undated, no envelope, but the mentioned exhibition is most likely "Cobra : Copenhagen, Bruxelles, Amsterdam : Art expérimental 1948-1951" which ran from 14 June to 14 September 1997 at Musée cantonal des beaux-arts Lausanne, then travelled to Hypo-Kulturstiftung (Munich, Germany) Kunsthalle and Kunst Haus Wien

It is presumed the letter would be to the organisers of the exhibition
