The Guerrilla Girls are anonymous artist activists who use disruptive headlines, outrageous visuals, and surprising statistics to expose gender and ethnic bias and corruption in art, film, politics, and pop culture. They work to undermine the idea of a mainstream narrative by revealing the understory, the subtext, the overlooked, and the unfair. The Guerrilla Girls have done hundreds of projects (street posters, banners, actions, books, and videos) all over the world—including retrospectives, traveling exhibitions, and interventions that have attracted thousands.
