I have never been to DL, but in my most recent trip to WDW, I acquired a pin, that looks a lot like the one on the bottom of the picture above (which I wore when I saw the movie in theaters. I got many strange looks!). I traded with a CM when I was in Disney Springs, and the back was not official. The pin does not have the markings of an average Disney pin, just ©Disney 2015, without the official pin trading logo. Maybe it's real, maybe not.
Good luck finding one!
UPDATE: I just realized that the day I got it was the first day Tomorrowland was in theaters. Maybe someone saw the movie, got the pin, traded with a CM, who later traded with me!
