The bulk of the collection comprises prints of photographs, 1968-2011, by Andrew J. Epstein. The majority of the materials, including photographs and text panels, were part of the 2009 exhibition "Queer Culture: The Photographs of A.J. Epstein." The photographs document LGBT communities in Chicago, New York, San Francisco and Los Angeles, 1968-2009. The collection also includes issues of Package magazine, for which Epstein was an art director.
