After a seven-year court battle with a German museum, thousands of posters seized by the Nazis in 1938 from Hans Sachs were returned to his heirs. The posters will be auctioned because no museum was willing to take the whole collection. “There’s of course no practical way that I could frame and hang 4,300 posters, so I just didn’t see any other alternative…” said Peter Sachs.

The collection includes a 1922 poster designed by Edvard Munch, an 1898 poster by the painter Gustav Klimt, and even James Montgomery Flagg’s 1917 recruiting poster, “I Want You For U.S. Army.”
