Yes, comic book panels! Those are the hand drawn/inked panels the comic book artists make before they are sent through the graphic editing/coloring/printing process. I bought a couple of those at a comic con last year... they were by Michael Zulli though (guest artist for Mirage). I have yet to get my mitts on Eastman and Laird panels (which prolly cost a fortune now!)
