Carter Reid and thezombienation.com
For those that aren't aware, the awesome cover for "Jean Archer: The Diamond and the Rough" was beautifully done by Carter Reid, creator and artist for thezombienation.com. If you haven't had a chance to read through and laugh at this slacker zombie web comic, I highly recommend it. I've literally laughed out loud while reading through this very entertaining ongoing story. Keep in mind, it's about a zombie slacker, so irreverence abounds, but that's part of its undead charm!
UPDATE: Carter has done the cover for “Jean Archer: All Fall Down”, and is planning on doing the cover for upcoming “Jean Archer: Here There Be Monsters”.
