In new introductions, authors Martha Cooper and Henry Chalfant recall how they gained entry into the New York City graffiti community in the 1970s and 1980s. New afterwords continue the story, tracing the decline of the subway and graffiti scene in the late 1980s to its unexpected rebirth as a global art movement. The authors reveal how the lives of the original subway artists have unfolded and mourn the loss of several to the darker forces of the street.
