One of Spain's top museums welcomed a U.S. court decision allowing it to keep a French impressionist painting looted from a Jewish woman by the Nazis, which the museum said it had bought decades later in a transparent way. Tuesday's decision by a California appeals court concerned one of the oldest Nazi art theft cases, which began in 2005 after the heirs of Jewish woman Lilly Neubauer brought forward an ownership claim for Camille Pissarro's "Rue Saint Honore, apres midi, effet de pluie" ("Rue Saint Honore, Afternoon, Rain Effect"), depicting a Paris street scene. "It is a regrettable story like everything else related to the Nazi plunder," the general director of Madrid's Thyssen-Bornemisza Museum, Evelio Acevedo, told Reuters.
