Today we have three vintage lenticular* pins from Disneyland. They are from the late sixties/early seventies. The Mickey Mouse pin above, is a personal souvenir of mine from a childhood visit to the park. This same version can be seen changing while worn by a "celebrity" park guest in this wonderful photo series posted recently by Daveland.
The Goofy pin below, belonged to my brother and was purchased during the same park visit.
Next, is the Tinkerbell version. I purchased this pin recently on ebay just to complete my collection. I believe there were only these three versions available....at least I only remember these three being sold at the park and I haven't seen any others out there for sale since then.
Below is a pic showing what the backs of these pins look like.
