Martha Cooper's photos take us through the Alphabet City of the late 70s as the area was about to undergo extensive urban renewal -- a process that is still continuing today. At the time, the neighborhood had more than its share of drug dealers and petty criminals, and the landscape seemed ugly and forbidding. But to the children who grew up there, the abandoned buildings and rubble-strewn lots made perfect playgrounds, providing raw materials and open space for unsupervised play. A crumbling tenement housed a secret clubhouse, rooftops became private aviaries, and a pile of trash might be a source for treasure. / Street Play is a photographic documentary centered on Martha Cooper's fieldwork in Manhattan's Alphabet City during the late 1970s. Through 120+ pages of black-and-white and color images, Cooper captures how children enacted creative, unsupervised play within a decaying urban environment. The book highlights themes of spatial agency, urban neglect, improvisation, and resilient childhood culture. It contributes to urban studies and visual sociology by offering visual ethnographic evidence of how marginalized youth appropriate derelict spaces, construct makeshift play structures, and create community. The editorial framing by Carlos "Mare 139" Rodriguez situates the work within graffiti and hip-hop precursors, emphasizing its role in documenting vernacular urban art and spontaneous street culture.
