These were given to me a long time ago from someone who return from vacation there. If official means produced with Disney's permission, I'm sure they picked them up as souvenir from there. I'll see if I can get that confirmed.
After looking the pins over really well, I have found none of the tell tale signs that would suggest they are fakes. They have a high gloss finish and no dimples in the material. They also have price tags from Walt Disney when they were purchased for 90 cents.
Wow. I never would have thought these pins be so popular. Thanks for verifying their authenticity for me. I suppose there probably wasn't a whole lot of fakes back in the 80s as there is now. I was given 2 sets of these pins.
