A 19th century painting by Polish artist Robert Sliwinski that was stolen by the Nazis during World War II was returned to its home country and presented to the public on Wednesday.
After a tip from Poland's Ministry of Culture and National Heritage, FBI agents recovered the painting in a town near Philadelphia, FBI spokeswoman Carrie Adamowski of the Philadelphia Field Office told NPR.
She said she couldn't comment on how the artwork made its way to the United States or when it was recovered. But Adamowski did say the person in possession of the painting didn't know it was Nazi-looted art and was cooperating with investigators. She also said that the U.S. Attorney's Office does not expect to file charges.
"We're just gratified that we were able to return to Poland a piece of cultural heritage," Adamowski said.
U.S. Ambassador to Poland Paul Jones joined Polish Culture Minister Piotr Glinski as the painting — sometimes referred to as Street With Castle Ruins — was unveiled in Warsaw. Three FBI agents from the art crime team who assisted in its recovery, Special Agents Jake Archer and Don Asper and Supervisory Special Agent Tim Carpenter, also attended the presentation.
