Oh, man, I almost wish you all hadn't said anything, the mystery pin does look quite a bit different (now that I've taken a closer look at it) from the PinPics one. I tried to find a pic of the pin on the disneypins.com website, but am having no success. Can anyone find a for-sure pic of the actual authorized pin? And does anyone have a pic of the backstamp of the for-sure authorized version?
I mean, either one or the other isn't quite right. There is no way that such huge color variations would take place in such a small Limited Edition production run. I actually kind of like the sparkly one better.
PinPics:
straight-through colors on trees and sky, easy to see flag stars, viewfinder is larger, star on Mickey's cap is filled-in, red steps are a straight-through color, Mickey's pants a bright-Navy blue
OP's pin:
trees & sky almost look sparkly, stars hard to see, viewfinder smaller, colors different - Minnie's shoes more purple than pink, Star on Mickey's cap is not filled in, steps look "sparkly" or multi-colored, Mickey's pants very dark blue

agnes!
