The three paintings won by the GI in the poker game, stored in a potassium mine for safekeeping during the war and then mailed home to his wife, are from an art gallery in the central German city of Dessau. The heirs of the GI and the librarian contacted the foundation last year amid publicity surrounding the release of the George Clooney film "Monuments Men," an adaptation of the book by the same name that memorializes the team of museum directors, curators and educators deployed to prevent the destruction of historic treasures during WWII.
