The Guerilla Girls are an anonymous group of feminist artists founded in 1985. They use art and activism to address issues of gender and racial inequality in the art world. Known for their distinctive gorilla masks and witty posters, they aim to raise awareness about the underrepresentation of women and artists of color in galleries and museums. Their work often includes statistics and provocative statements, challenging institutions to confront their biases. The Guerilla Girls have created campaigns that highlight the disparity in exhibition opportunities and art sales, making them influential figures in contemporary feminist art and activism.
