The FBI has announced the return to the Polish government a painting from the 16th century believed stolen by the Nazis during World War II. Agents say the painting entitled "Portrait of a Young Man" by Krzysztof Lubieniecki was brought to the U.S. by a service member and later sold to art collectors in central Ohio who weren't aware of its origins. A relative of the service member discovered the painting's background while conducting genealogical research. John and Janice Bobb of Westerville purchased the painting from the service member's widow through an agent.
