1.25" as issued without a backpaper but with maker's name on curl "By Stanley-Toronto." Button is from the mid-30s issued to promote a gingerale soda product with the text reading "Gurd's Mickey Mouse Club." Beneath Mickey's feet is additional tiny text "Copyright Walt Disney Enterprises." Tiniest traces of wear under magnification but button is Exc. and displays Mint. Only the second example we've seen. Our first several years ago reached almost $900.
