1.25" celluloid of Buster and Tige in superb color. Underside is open with spring steel insert that produces small clicking sound when pressed. From early 1900s with maker's name Ehrman on curl. Four tiny dots of missing celluloid on Buster's face but they are so small they are for practical purposes not visible without magnification. Entire celluloid is bright and clean with perfect centering and high gloss. About the third we've seen. Rare.
