I know I have Steven Hughes (RIP), Mark Waid, Dan Jurgens, Tony Daniel (and a neat-o Cable 8X10 sketch by Daniel), George Perez and I'm pretty sure Jim Lee if I remember correctly. I better crack open the safe to double check that. I also have some more that I can't think of off hand right now.

I don't sell anything under $10. It's not worth my time.
