The National Gallery of Art has acquired works by three contemporary female artists and a Chicago outsider artist using funds from the museum’s Collectors Committee and other donors.

Cecily Brown’s painting “Girl on a Swing,” Martha Rosler’s photomontage “Cleaning the Drapes” and Roni Horn’s cast-glass sculpture “Opposite of White, v. 2” were added to the collection at the museum’s board meeting May 1.
