Until they sell out, every copy of Incredible Doom Vol. 1 at BuyOlypmia.com is signed by me and features a sketch of Allison like the one here. On top of that, they are on sale!
I don't make any money on these. I love BuyOlympia. While you're there, check out some of the fantastic artists. For example, I've sent some of these postcards by Lucy Bellwood.
