13/16". Image of Donald w/"Member" banner across his body. Maker name of "Smith Bros. Sydney" on the curl. We have only seen one other in our 57 years and that had a different issuer imprint, "Regent Theatre." That was back in 2008 and it was also in much lesser condition w/notable staining. This button has much of the silver flashing off the metal back. Rim curl has some pinpoint age dots but front remains bright and glossy. VF. A Disney button rarity.
