Who is in the bottom left corner of the giant Marko Djurdjevic Wolverine poster?

I'm looking everywhere for who this is, and what era of Wolverine this is from and I can't find anything. The picture appears as a variant cover of Uncanny X-Force #3. You can view it at http://www.razorfine.com/wp-content/uploads/2011/01/uncanny-x-force-3-cover.jpg
