Fire at Sea...you’re looking at the original artwork and the matching card set that captures one remarkable piece of military training. See the blast of flames. Talk about being prepared! On the back of the card is the story of how carefull rehearsal of the crew for a real fire onboard could make all the difference between life and death at sea. This is one reassuring piece of original artwork from the Uncle Sam Trading Cards World War II military series produced and issued by GUM, Inc. of Philadelphia. All these military training maneuvers were part of the successful series of gum cards. This one is the original 7 1/2 x 9” (approx)artboard consisting of the black ink drawing as well as the color overlay that was used to print the included Uncle Sam Card #21.
