The Guerrilla Girls are a bunch of anonymous females who fight discrimination with facts, humor and fake fur. They take the names of dead women artists as psuedonyms and appear in public wearing gorilla masks. "The Guerilla Girls' Art Museum Activity Book takes you behind the pretty pictures. Wallow in the dirt that muesums hope you haven't noticed. Take our fun tests; do the math. Get ideas for how you can bother, and maybe change your favorite museum, just like we've been doing".
