"The Photographic Object, 1970"

MoMA's revival of L.A. artist Robert Heinecken seems to have set off a scramble for others who similarly toyed with fusing photography and sculpture some 40 years ago. This show, which includes Heinecken, manages to track down 13 of his contemporaries, most of whom also hailed from the West Coast. Their efforts could seem highly provisional, though works like Ellen Brook's idyllic nude couple on a lawn made of actual AstroTurf testify to the ingenuity involved in pushing 2-D photos into 3-D.
