We got one during Millennium Celebration. I think it was $38 for the image of the two of us (the single most hideous photo we have ever taken and, although we may not be supermodel material, we both usually take a good picture). The image is about an inch square. They give you a locator--but I think it was mailed to us after. There was a website for it too--don't know if it is still active. Anyway, we make a habit of visiting the ugly thing as soon as we get to Epcot. This year, we will have the pleasure of frightening four family members with a viewing.
Oh, we also got "Leave a Legacy" pins, which were cool because I collect pins. That's all I can remember, hope it helps.
