Ben Templesmith tweeted a sketch he did of Wolverine that he offered up as line art for any aspiring colorist to practice on. BleedingCool.com reported it here and guessed that it might be a future cover, which Templesmith later shot down.
I know we just had Old Man Logan, but with how much this reminds me of Paul Pope's work, I'd definitely buy a Batman-Year-100 style Wolverine mini with Templesmith on art.
