Before the Andy Warhol photography exhibition ends, bring a can of soup (Warhol made the Campbell's Soup Can a famous art icon) or other nonperishable food items to the Ulrich Museum as a donation for the Kansas Food Bank. Museum staff will collect donations through Friday, Dec. 18, the last day to see "Snap: Andy Warhol Photographs, 1970-1987," an exhibition of Polaroid photographs that include actress Liza Minnelli and hockey star Wayne Gretzky.
