These were fun to collect from Coke bottle. There was a thin plastic film over each pic that had to be peeled away. Can't remember what prizes were awarded for the promotion.
I believe I got these from the Tahitian Terrace back in the day. Some still have suger in them!
I have a question about this in another thread, but I believe it is from the Disneyland Hotel. (I will edit this if that proves not to be factual)
Mickey Viewmaster and some of the reels. Used to spend a lot of time looking through those reels!
