The mother of graffiti, a living legend, the documentary photographer who spread to the world the graffiti hip hop movement: Martha Cooper. It wouldn’t be an overstatement if we said that nearly all the writers and street artists we know today do what they do thanks to her. In the 70s, a then insular underground movement was documented by her, which lead to co-publish (with Henry Chalfant) the graffiti bible: Subway Art.
