This is a special little sheet of stickers!
It is printed on holofoil material that has various geometric sparkling shapes in it. This makes it cool to see, but difficult to photograph. The graphics' ink lays on top of the foil (and is sometimes a little transparent, which may let the sparkles through just a bit) There is one big main sticker with the title-screen type graphic (though Segasonic is on the banner) and 4 smaller stickers below it. There's a blue flicky bird, roller the badnick, Picky the pig little animal & chopper the fish badnik. Only Sonic 1 enemies & animals indicate that this sticker set came well before Sonic 2, so it's quite an early item.
