Lever No. 3, 1989
Carved and painted wood
National Gallery of Art, Washington, D.C.
The Washington Post today ran a special section on Feminism and Art, which included a full page feature by the Guerrilla Girls, a group of artists that works to draw attention to discrimination in the art world, which pointed out that the National Gallery of Art currently has only one work by an African American artist on display. I don't know if that's true or not, but this is the only one I could find in my brief exploration of the NGA website. (I won't claim to have made an exhaustive search, though.)
