Apparently the guy who did the Wolf artist is a famous guy in Sweden. The band liked his stuff, but taken out of context and put on a metal sleeve where it's going to be bought by people who have no idea who he is it does look fairly ridiculous..
I've seen worse though. Try Hawaii's "The Natives Are Restless", Hallows Eve's "Tales Of Terror" or, worst of all, "In The Name Of Metal" by Executioner.
