Here are Tomy's Classic Style Sonic & Tails plushes as a fan photo in a store. Hot Topic, to be exact. They look decent enough here. Sonic is posed, with one fist stitched to his hip & the other arm up with a pointing finger. His ears are just flat…
This keychain isn't officially Sonic, but it was a part of a Sonic promotion when the Sega Dreamcast came out. You can sort of see the reddish/orange-ish swirl on it.
