This collection contains photographs of the Fairmount Park system and Philadelphia recreation facilities created between 1855 and 2012, primarily photographic prints with some slides, negatives, contact sheets, and transparencies. The collection consists largely of 8 x 10 inch prints documenting park features such as historic houses, guard boxes, landscapes, construction, and demolition, as well as recreation centers, playgrounds, pools, and recreational programming, though sizes and subjects vary throughout. Materials include official photographs from both the Fairmount Park Commission and the Department of Recreation, along with related materials accessioned for their informational value. The breadth of subject matter supports research in Philadelphia's recreational, architectural, landscape, and social history.
