Don't know about the other covers, but the Vampirissimo issue with the bear on the front is a possible rip-off of Frank Frazetta's 1974 painting "The Bear." I wonder if the rights to that work were sold to this publisher.
Good eye. There are a few swipes from Frazetta' and Warren Magazines on covers from around the world. Most are more blatant than this example.
