In contrast to the decades-long court battle fought by a Pasadena museum with the heir of an art dealer to keep a pair of $24 million, 400-year-old paintings which had been seized by a Nazi leader during World War II, the Virginia Museum of Fine Art Board voted last week to return a valuable painting it had acquired under similar circumstances. The masterpieces in both cases had been taken in forced sales from Amsterdam art dealer Jacques Goudstikker in 1940 by Hermann Göring, Hitler’s henchman who created the Gestapo, the feared Nazi secret police.
