The tanks in the background are advancing. Up close, the military is taking aim and firing with precision accuracy. The sound of the artillary blasts are ear-shattering...and this is only a piece of artwork!! Take a good look. You can see how this piece clearly focuses on the training to make sure that the job gets done right. This is one powerful piece of original artwork from the Uncle Sam World War II military series produced by GUM of Philadelphia. All these military training maneuvers were part of a 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 matching Uncle Sam Card.
