PINAR DEL RIO , CUBA – A traveling exhibition of art donated by a U.S. philanthropist Gilbert Brownstone, is giving Cubans outside the capital a rare chance to see works from masters such as Pablo Picasso and Andy Warhol that would normally hang in world-class galleries instead of sleepy provincial cities. Selections from the 120-piece collection have already toured Camaguey and Holguin in the island’s far-flung east and recently went on display in the western city of Pinar del Rio, known more for tobacco farms than art museums. More than a dozen works by Joan Miro, Marcel Duchamp, Salvador Dali, Camille Pissarro, Georges Rouault, Roy Lichtenstein and others went up in the glassed lobby of a local TV station, watched over by just a few police and guards and prompting curious passers-by to pop in to see what all the fuss was about.
