In 1985, a group of vigilantes wearing gorilla masks took to the streets. Armed with wheat paste and posters, the Guerrilla Girls, as they called themselves, set out to shame the art world for its underrepresentation of women artists. Their posters, in the words of one critic “were rude; they named names and they printed statistics. They embarrassed people. In other words, they worked.” In addition to posters (now highly-valued works of art), billboards, performances, protests, lectures, installations, and limited-edition prints make up the Guerrilla Girls’ varied oeuvre. Their unorthodox tactics were instrumental in making progress. The group is still going strong, reminding the art world that it still has a long way to go. Referring to themselves as “the conscience of the art world,” wherever discrimination lurks, the Guerrilla Girls are likely to strike again.
