Before the 1960s, few museums or collectors acquired photographs or considered the medium as an art form. The moment arrived, however, when photography's profile ascended and the medium began to gain widespread acceptance. This catalogue publishes for the first time the 548 photographs in the Norton Simon Museum of Art collection, more than 90% of which were acquired during that fascinating moment of transition in the history of photography, 1969 to 1974. Published in association with the Norton Simon Museum.
