Black Pulp!, the exhibition organized by artists William Villalongo and Mark Thomas Gibson makes connections between artists as disparate as Afro-futurist Philadelphia bandleader Sun Ra and Krazy Kat cartoonist George Herriman. It gathers posters, book jackets, album covers (of Michael Jackson, Donna Summer, and Kurtis Blow), comic books, and work by artists such as Kara Walker and Kerry James Marshall in exploring issues of identity and race in American pop culture. Through April 29 at the African American Museum in Philadelphia.
