What a lovely find—reproductions of collages by Man Ray. Currently part of 1913: The Year of Modernism exhibit at Princeton, on until June 23, 2013.
Between 1916 and 1917, the artist and photographer Man Ray created a series of collages he called "Revolving Doors." He included the series in his third solo exhibition at the Daniel Gallery in New York, in 1919. The collages, whose geometric shapes combine machine-like and anthropomorphic forms, were framed and installed on a rotating pole that the viewer could spin. The original collages were destroyed, but Ray later reproduced them in this series of stencil prints, published by Éditions Surréalistes in Paris.
