Electronic Gaming Monthly (the now out of publication USA magazine) released a freebie sticker set to celebrate Sonic Adventure 1. This would be enclosed with an issue of the magazine in a bag. The sticker set is pretty cool, as you get all the new-style art for the characters. Wierd-walkin' Sonic is largest, but they also thought to make the Tails pretty big too, which is a good touch. If you look closely, you can see they included E102-Gamma which is great because after this he was pretty well neglected. This is definetely a cool sticker sheet to collect, if you can find it.
