You may have seen Andy Warhol's paintings of Campbell's Soup cans or a handful of his silk-screened images, but beginning Sunday, SFMOMA offers the chance to explore Warhol's life "From A to B and Back Again." The exhibit contains more than 300 works from the duration of Warhol's four-decade career. We'll talk about the exhibit, which runs through Sept. 2, with Donna De Salvo, who curated the exhibit for New York's Whitney Museum of American Art, and Gary Garrels, the senior curator of paintings and sculpture for SFMOMA.
