This product is a large vintage U. Navy 1st Class Diver plaque made of aluminum mounted on wood. The plaque is a military collectible item representing the Navy force with a theme of militaria. It originates from the United States, adding to its historical significance and value as a patriotic piece for collectors or veterans. Measures 19″ x 16 5/8″. I don’t know the year or era but it’s definitely vintage.
