Since Thursday, the white walls at Eric Firestone Gallery have been wholly devoted to just a small portion of Henry Chalfant’s  archive of “subway photographs.” Henry Chalfant: 1980 focuses on a year in which graffiti was still regarded as subversive and dangerous. At the same time, street art was at its most vibrant and anarchic. The work offers not only a trip back to the “golden age of graffiti,” but a thorough “visual anthropology,” as Chalfant describes it– a studied view of street culture back when it actually came from the streets.
