Artist is Tony Moore.
Interesting. It totally jumps out at me as Stokoe. Love the detail in that cover. Me likey too. 
I thought you meant the symbiote/punisher mashup character at first… but when I googled it the artist came up…and yes it looks a lot like his work…
…unless the email I got soliciting it is wrong.
Tony Moore artwork is awesome… it was a shame he couldn’t keep up with Kirkman’s demands… he puts out quality work. Imagine if we got Tony Moore the entire run of Walking Dead… it would have been so much better, even when the story was getting kind of redundant and boring…
Yeah that codex variant is sweet!
Never go full blackface!
