● Original dual tone lithograph exhibition poster by Robert Morris. 93 x 60 cm, in very good condition. This is the original of Robert Morris' historic, highly collectible and controversial advertisement for his New York Castelli-Sonnabend exhibition from April 6-27, 1974. According to Wikiart, the original poster was part of Robert Morris' "continuing dialogue with the artist Lynda Benglis, with whom he had previously collaborated on film projects. In the ad, featured in Artforum magazine, Morris is seen from the waist up, flexing his muscles and outfitted only in S & M gear: a German Army helmet, aviator sunglasses, steel chains, and a spiked collar. While striking in itself, Morris's hypermasculine self-portrait is important for prompting an image that gave rise to a huge controversy on the pages of Artforum: a centerfold ad in that same magazine featuring a photograph of Benglis, naked but for a pair of sunglasses, a diamond earring, and sporting an enormous dildo. While Morris's image barely raised an eyebrow, "the Benglis ad" was met with an angry uproar that dramatically illustrated the sexual double standard. Interestingly, one of the loudest voices of condemnation against was the art critic Rosalind Krauss, who had actually photographed Morris for the Castelli-Sonnabend poster; along with other editors of Artforum, Krauss called the ad "an object of extreme vulgarity" that succeeded in "brutalizing ourselves and, we think, our readers."." Robert Morris (February 9, 1931 November 28, 2018) was an American sculptor, conceptual artist and writer. He was regarded as having been one of the most prominent theorists of Minimalism along with Donald Judd, but also made important contributions to the development of performance art, land art, the Process Art movement, and installation art. Morris lived and worked in New York. In 2013 as part of the October Files, MIT Press published a volume on Morris, examining his work and influence, edited by Julia Bryan-Wilson.
