I'll probably repeat this sentiment in the future but I have to say that the upcoming Gahan Wilson collection is a bit of a dark horse for me. I was never exposed to much Wilson work before beginning on this project and every day I'm floored by it. Gahan Wilson's work is easily some of the most consistently funny work I can imagine. If your bent is at all towards macabre humor this is one you want to start saving up for.
And, hey, it's a great gift for new parents too!
