Here are some Sonic X-Treme stickers. They're so Xtreme in fact, that they are xtremely hard to see. Of course X-Treme was the late 1990s or so game that never got made. The sticker set has its logo on 2 of it. The others show rainbow colored line art of Sonic doing varoius things they think are 'xtreme' such as kicking a soccer/football, rollerblading, some kind of martial art & something you really can't see too well. The card at the top says "On the Edge Movement Stickers With Attitude" which is borderline engrish. PrimaJuice may be the maker. It's not common, so it goes for about $10 Australia dollars. The art is rare too, since the game never got made & the style is classic but unusual. This is an unusual & interesting set to collect.
