The building, which shuttered in the late 1990s, had become a squatters haven, a popular space for junkies and graffiti writers. Theresa Stigale took a tour of the building in 2003—and her photos show it. (In the best possible way.) Her photos have a certain pixel-patina, with post-processing she describes as “Instagram before Instagram.” This is her gallery.
