This is a very interesting 2-sided tee. Quite different from just plastering stock art onto anything they find, real design actually went into this. The background is somewhat surreal, but done in a 'scratchboard' style with thin lines (as in linescreen type) making up the shaded areas. You've got the checkered pattern ground, sketchy mountains, some rings and even the polygonal bent-paper looking
palm trees, streight out of the game. The Sonic art really stands out here, because he's full-color, while the rest is a muted blue-gray. (it says "Sonic" in small text near him) This shirt is sure to be an interesting point in your collection, if you can find it. It was not common.
