In Focus: 75 Years of Collecting American Photography
From the website: In 1934, when the Addison Gallery purchased a photograph by Margaret Bourke-White, it became one of only a handful of museums in the country to seriously collect photography. Seventy-five years in the making and consisting of more than 6,000 images dating from the 19th to 21st centuries, this collection represents one of the major repositories of American photography.
