Back in April, Swiss prosecutors raided facilities at the Geneva Free Ports and seized Amedeo Modigliani’s Seated Man with a Cane. The painting, which once belonged to the Parisian art dealer Oscar Stettiner, has been at the center of a lengthy legal battle led by the original owner’s grandson, who claims that the work was stolen by Nazis. The painting’s current owner, David Nahmad, spoke out last week, stating that the $25-million work has not been proven to be Nazi loot.
