Guerrilla Girls first rattled the art world in New York 1985 with street posters calling out galleries, museums, collectors and press for discrimination. The collective has included over 55 members over the years, some for weeks, some for decades. Their anonymity keeps the focus on issues and away from the individual identities. They wear gorilla masks in public and use facts, humour 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 advocate for intersectional feminism that fights discrimination and supports human rights for all people and all genders. They 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. They also do projects and exhibitions at museums attacking them for their discriminatory practices right on their own walls, including their 2015 stealth projection about income inequality and the super rich hijacking art on the façade of the Whitney Museum in New York. Their retrospectives in Bilbao and Madrid ‘Guerrilla Girls 1985-2015’ and their US travelling exhibition ‘Guerrilla Girls: Not Ready To Make Nice’ have attracted thousands. They are also up for international bookings. They could be anyone. They are everywhere.
