London: Gallery One, 1957 (06), 9×18 cm [folded]. Bifolium. Oblong invitation card for an exhibition of monochromatic works. It was in London about a decade earlier (1946) that Klein claims to have executed his first monochrome paintings [Held, 1995]. First page contains exhibition info and announces also a public discussion that is to take place with Klein and Restany “due to the controversial nature of this work” a couple of days after the exhibition’s opening, finally ‘Pernod and red wine’ is promised to attendees. The card opens up to a 2 page text in English by Pierre Restany titled an Act Of Truth. Final page blank. This particular card is an example of special interest bearing the blind stamp of Jean-Paul Ledeur, an expert on Yves Klein and author of the Catalogue raisonné des éditions et sculptures by Klein.
