1-1/8" with image of Buck holding his rocket pistol. Complete text reads "I Saw Buck Rogers 25th Century Show Did You? A Century Of Progress 1934." Bottom right cream outer edge has hardly noticeable .25" hairline where the cream paint did not take during manufacture. Other than this, the entire face of the button is about as Mint as possible for a litho with no visible paint loss and exceptionally high gloss. The only other paint defect is on the side edge of the button, just a small scratch about 1/8" long that doesn't show at all from the front view. A rare souvenir from the Buck Rogers exhibit on the Enchanted Island. N. Mint.
