At the SDCC this summer, fine artist and painter George Pratt was set up way toward the back end of artist alley. I don't know how often George does shows, but this was the first time that I'd seen him set up. More known for his paintings then sequential art, Pratt had a booth with several painters working with him...and all week long they just sat and did oils and worked with charcoal on canvas.
These four were all signed and sketched, including the balance of the "Shaman" storyline he did for the first arc of the title. I know Cos has the only sketch cover by Pratt, and looking at census, these look to be four of the only five in 9.8 s/s with the first being an Ed Hannigan.
