Beneath the Streets reveals the world of street art and graffiti writers in the depths of the New York subway for the first time with fantastic photographs captured from throughout the tunnels and byways of the underground. Although it provides service to over five million riders every day, the subway is for most a sealed system, very few of its patrons are aware of the extent and look of this vast underground infrastructure. The authors of this important historical work found that photographing the graffiti in these passageways brought to light a hidden new artform.
