This is a rather interesting old shirt, with its extreme shading and all-over design. The "zone" in the background has some trees and the classic checkered ground, but everything is all done in purple.
Sonic is the usual running stock-art, but they've done an almost noir-ish job of shading it by adding extreme darks and purple shadowing all over it. This gives the shirt a dim-spotlighted feel that is rather unusual. This shirt was not common.
Tails did not appear often on early merchandise, and that might be a GOOD thing, if this shirt is any indication. Regular finger wavin' stock art Sonic is pared with a too-small, brown, needlessly-flying Tails. This is the rather mutated stock art, with eyes looking in the wrong direction, fat shoes and globby head. It's a far cry from the cute Tails appearing in Japan at this time. The background is a series of yellow rectangles, perhaps supposed to be from a zone.
The shirt itself is nice, with an interesting red top, cut in oddly with gray to make it different. The regular logo appears large, as a part of the design.

Here's a really curious piece, no doubt from the 1990s. It's clearly modeled after a motorcycle jacket, with charcoal and black for the sleeves.
It's also clearly trying to knock off Harley Davidson, with the shape of the logo and prescence of the bike. Sonic is dressed...a LOT. Possibly the most ever, as he's now covered head to toe in something all new. This was RARELY done (and is actually a hallmark on some fakes!) due to the desire to keep brand identity strong with Sonic's image. They've pitched it all out the window here, with his black leather high-tops, pants, white tee and motorcycle jacket...plus sunglasses! It's also rather nonsensical, as any motorcycle would be FAR SLOWER than Sonic! Perhaps it's an image thing...
Conspiracy Theory Hats = ON!
Is this shirt throwing Archie Comics a bone? Their "Alternate Reality Evil Sonic" started out as an all-leathers wearing 'dude' with sunglasses, just like this one here. The answer is 99% "No" the shirt is likely just a gimmic. Little kid sizes & quite uncommon.
