The Guerrilla Girls are feminist activist artists. Over 55 people have been members over the years, some for weeks, some for decades. Their anonymity keeps the focus on the issues, and away from who they might be. They wear gorilla masks in public and use facts, humor and outrageous visuals to expose gender and ethnic bias as well as corruption in politics, art, film, and pop culture. They undermine the idea of a mainstream narrative by revealing the understory, the subtext, the overlooked, and the downright unfair. They believe in an intersectional feminism that fights discrimination and supports human rights for all people and all genders. Guerrilla Girls have done over 100 street projects, posters and stickers all over the world, including New York, Los Angeles, Minneapolis, Mexico City, Istanbul, London, Bilbao, Rotterdam, and Shanghai, to name just a few. With projects and exhibitions at museums, the Guerrilla Girls attack them for their bad behavior and discriminatory practices right on their own walls.
