This is the "Sonic & Knuckles Le Guide Ultime" (Ulitmate Guide, probably) made by Cyril Direct. It's probably just a regular game guide (like all those Brady Games ones that get made) but the cover sure is odd. Look at stock art copy...sorta Knuckles with his super small fists. He's clearly standing on Robotnick's giant butt/back area? It's hard to tell because his arms are growing out of his neck, while his mustache has somehow gotten BEHIND his head. Sonic doesn't fare much better, he has a huge wierd mono spike thing, blobby body & strange shoes. Why does he have Robotnick on a leash? Is that a blue ribbon he's holding? It's like the illustrator they got barely had a grasp of anything before doing the cover. It's just very strange & indicates nothing of what the game might be like. Hopefully the interior is actually useful and not so strange.
