Can Erotica Save the Art Market? Girls, girls, girls. Can erotica save the art market? The answer would seem to be "yes" based on the results of the three-session sale at Christie’s New York of the Constantiner Collection of photographs, Dec. 16-17, 2008. Assembled by New York art patrons Leon and Michaela Constantiner, the collection focuses on glamour, and includes photographs of high fashion models, often in states of undress, as well as a large selection of images of Marilyn Monroe and an assortment of erotic fashion shots by Helmut Newton. Other photographers in the collection include Richard Avedon, Guy Bourdin, Irving Penn and Herb Ritts.
