Leinil Yu, Travis Charest, and Mike Deodato for Wolverine.
So many great artists have done their take on our mate Logan. My favorite artist is Jae Lee but I also love many others and especially Deodato. Adam Kubert is one of the best Wolverine artists and did one sick cover for issue #300. I'm hoping to get custom sketches done on blank covers I have by Yu, Deodato, Kubert, and Lee at some point.
@irishx: Indeed man! I recently picked up Origin II #1, and Kubert's still got it! Art was all around beautiful. He and his brother Andy (Who did Origin back in 2001) are awesome with Wolverine. Steve Mcniven also killed it with Wolverine back in Old Man Logan. So many artists have indeed left their artistic stamp on Logan over the years.
