These packs of pin badges / button pins are available for sale at the Alton Towers Hotel (the one with the Sonic themed room & roller coaster) Each pack contains 4 pins, and can be found in the shop. One set is modern and has CG art from the games (Eggman, Sonic, Tails, Knuckles) the other is classically themed, and uses re-touched stock art & 'new classic' art--all of Sonic, & then one with the logo. The backs of the cards reveal the maker "GB Eye". The copyright info is on the badge-edge so it doesn't disturb the art. These can also be bought at www.play.com , if you can't get to Alton Towers.
