Charlie Adlard (chromium wraparound)
As a bonus a very limited edition 12th variant will also be issued but will only be available to fans who buy tickets for the zombie-filled The Walking Dead Escape obstacle course event, which is taking place at San Diego's Petco Park on the Thursday, Friday, and Saturday of Comic-Con weekend. The good news is that Kirkman's Skybound imprint is giving away the comic for free to "Survivors," "Walkers,' and spectators. The bad news is won't be attending and I'm jealous to anyone who gets to participate in this crazy event!
