When Sega celebrates the 60th Anniversary, they released this set of 7 'rubber keychains'. This is likely that flat cut-in rubbery texture plastic that captures detail well. The first 2 are Sonic, with genuine classic finger waving Sonic, then the Japanese stock art of 'getting ready to run' Sonic. Tails is likely also classic-classic, where he's looking back with his hands behind his back. Knuckles is the first art they ever really published of him. Tails flys carrying Sonic is neoclassic. Sonic in the winged ring is from the game title screen, and Eggman in the Egg-o-matic but his pointing forward is probably also neoclassic. They're lively and fun designs that work well as a call back to 'early Sonic', but are kept fresh with new art as well. A good set, but where was it sold?
