From 1975-1977, Larry Sultan and Mike Mandel selected photographs from a multitude of images that previously existed solely within the boundaries of the industrial, scientific, governmental and other institutional sources from which they were mined. The project, “Evidence”, was funded by a grant from the National Endowment for the Arts, and was one of the first conceptual photographic works of the 1970′s to demonstrate that the meaning of a photograph is conditioned by the context and sequence in which it is seen.
