A sumptuously produced, slipcased compilation of the ambulatory minimalist's letters to Yvon LambertAndré Cadere (1934-78) strove to remove art from the restrictions of museums and galleries. He is best known for his "Barres de bois rond" (round wooden bars), which he would carry to public spaces and exhibition openings. Between May 19 and July 3, 1978, Cadere wrote 43 letters to his friend, the gallerist Yvon Lambert, when Lambert came to visit the artist at the University Hospital in Paris.A precious testimony to Cadere's thought and art, these letters are published here for the first time, in their entirety. This edition consists of a slipcase containing the book, which features an introduction by Bernard Marcelis, a specialist in Cadere and author of his first catalog raisonné, followed by the 43 letters with commentary, annotated by Marcelis and illustrated.
