Looking at the work of the anonymous female artists and activists group the Guerrilla Girls, “Takeover” (on view at Nasher Sculpture Center through August 29) highlights the group’s campaign for spreading awareness surrounding the inequities in the art world. Starting in 1985, the group was known for plastering the surfaces of New York City (as well as locations internationally, like London, Shanghai, and Los Angeles) in stickers, posters, and other public displays featuring bold graphics, satirical wording, and statistics to shine a spotlight on the gender and racial discrepancies found among the art community.
