This is a photograph of a sculpture by Alexander Archipenko, which historian Stephen Kern describes as reversing "the traditional notion that space was a frame around the mass, that culture begins where material touches space, and maintained "that sculpture may begin where space is encircled by the material."" (Kern 1983, 159).
