NASHVILLE, Tenn. AP – An 82-year-old Holocaust survivor and his family are suing the German government over an extensive art collection, including paintings by El Greco and Peter Paul Rubens, seized by the Nazis and sold at auction during World War II.

The lawsuit is unusual because it is seeking damages for lost art rather than the return of items that once belonged to Holocaust victims, lawyers said. The suit estimates the 400 or more works would be worth “tens of millions” of dollars today.
