2.25" showing Gene next to Champion. No maker and no backpaper. From the 1940s. Bit of dark brown spotting on the first three letters of his name, two spots on Champion, and a .5" dia. area blending with the black color at the center left. About 90% of the button remains clean and glossy. The irregular black line around the outer edge is as designed. Most likely produced as a c. 1940 rodeo souvenir button. Only example known to us.
