There is an Ashley Wood original painting for sale, its from his Uno Fanta book. Its oil on paper, is is 18″ by 24″. There is some tape left on the paper, but it kind of ads to the piece, and if you really hated it you could matte over it.
He also has some prints on his site, I wrote about one in the last SFWeekly article. They are poster prints but are huge and signed, and on good paper. I have one on the way, so ill write more. I couldn’t pass it up, they’re only $10 before shipping.
