Guerrilla Girls
[ɡəˈrɪl.ə ɡɜːl]

The Guerrilla Girls are feminist masked avengers in the tradition of anonymous do-gooders like Robin Hood, Wonder Woman and Batman. They are best known for expose sexism, racism and corruption in politics, art, film and pop culture and do so with facts, humor and outrageous visuals. After 3 decades they are still rattling art world cages.
