Continuing on the gun thing that seems to be going on around here, I thought this image by Man Ray would make an excellent re-introduction of the Art Piece of the Week.
Man Ray (American, 1890–1976)
Ford Motor Company Collection, Gift of Ford Motor Company and John C. Waddell, 1987
It is located in the Metropolitan Museum of Art's permanant collection in New York City, in case your interested.
