This 13/16” litho by Greenduck features the primary mushroom character from Disney’s 1940 Fantasia movie. Button was likely issued in 1940 or early 1941 to benefit as the rim text says “United China Relief.” Button has just a couple tiny pinpoint dots of paint missing largely from the lettered area and blending very well. Beneath the image is tiny text “©W.D.P.” One of just a couple known and one of the rarest Disney pins, the first we’ve seen in decades.
