For decades, Bill Cosby and his wife, Camille, have built one of the world’s most celebrated collections of African-American art. While their collection usually resides in their home, in celebration of the National Museum of African Art’s 50th anniversary, they’ll loan the the pieces to the Smithsonian for the next year.
