By far one of the coolest things I've ever had the privilege to own! It popped up on the USMF facebook page, and I snagged it about 5 minutes after it was posted. The original artwork was likely designed by Hank Porter, a Disney animator, in early 1944. It was painted on wood by CPL. Harold R. Kingsbury. It measures about 3 feet wide and 3.5 feet tall.
Thanks to disneydave for all the help.
