1-1/8" litho w/image of Buck holding his rocket pistol. Complete text reads "I Saw Buck Rogers 25th Century Show Did You? A Century Of Progress 1934." Paint is 99.8% flawless w/high gloss, however, far right side has narrow and shallow 5/16" dent diagonally on helmet. This will show in certain light angles and in others doesn't show at all. Still a beautiful example, particularly for a litho tin button. Visually among the best three of the six we've seen. A rare souvenir from the Buck Rogers exhibit on The Enchanted Island.
