In 1970s New York, Martha Cooper captured the birth of the global graffiti art movement. Decades later, she is celebrated as an icon, and at 75 years of age she continues to document not only the dynamic street art but has also produced decades of photographs that capture the humanity and joy of people living on the fringes of society, within subcultures that, if not for Martha, would remain unseen.
