7/8" w/back paper by Phila. Badge which has small and minor moisture stain on upper left edge. Button names the licensed product and tiny text below Mickey's feet reads "Copy. 1928-1930/By W.E. Disney." This is the earliest version and a design we've seen only a couple of times in our 57 years. The typically seen and much more common version, probably introduced about 1932, is a bit smaller and depicts Mickey in red pants. Bottom curl has a faint tiny tan dot beneath the letter "U" but essentially invisible when the button is viewed directly. Still glossy and Exc.
