NEW YORK (AP) — A collection of rare posters seized from a Jewish collector by the Nazis is up for auction.

Hans Sachs started collecting posters as a teen and became Germany's leading private collector with 12,500 posters. The Nazis seized the collection in 1938.

His grandson Peter Sachs went through a legal battle for several years to get what was left of the collection back.

Just over 1,200 have been put up for sale at Guernsey's. Details of the three-day auction, which started Friday, weren't available Sunday night.

The collection includes a poster that Edvard Munch designed for an exhibit of his own works in Zurich in 1922, an 1898 poster by Austrian symbolist painter Gustav Klimt, and James Montgomery Flagg's 1917 "Uncle Sam" recruiting poster "I Want You For U.S. Army."
