I think I saw some for sale on eBay this week. Marc Miller (yes THAT one) is selling them under his alias there, along with a bunch of signed Keith artwork. Here's his current auction list. Of course now that I've told everybody here I have no chance of them fitting in my budget oh well.
Hey! Maybe I get a finder's fee
Here's a direct link to the Deitrick Gamblers I was looking at. There might be more there or to come later.
Of course the one I really wanted was The Girl but at $41 its over my budget Not that its not worth every penny it gets mind.
