How about the Zellers labels and the Taiwan pirate labels? I think you can find scans on this site.
What's especially interesting, is how silly some of the Taiwan labels are. Take Popeye. He looks like a fat guy who likes to eat and stuff in their illustration. Even worse, they screw up on the names and everything. They don't even call the spinach "spinach" either. They call it cabbage. Also, there's this pirated alien game with a label illustration that says something like "E.T. GO COME!" (should be "go home," but... this sounds even sicker than the concepts behind those Mystique games. GO COME! hehehehe)
And of course, the Taiwan "Chess" game, where they have the 3-D Tic Tac Toe label illustration, but the game is actually Othello.
The Zellers "Farmer Dan" illustration is actually ripped from Activision's Plaque Attack game (Farmer Dan is actually Gopher I think). And "Challenge" is nothing like its cart label illustration, which looks like a scene from Ghostbusters.
