Mike Mignola and I were guests at a terrific convention in Birmingham, England last year and we were asked to do this piece for their program book and charity auction. Mike pencilled the Hellboy figure and sent the board to me so that I could draw Jack and ink the whole thing.
That big empty space in the lower right bothered me so I added another contraption to fill it up.
Most people didn't even realize that I'd inked the Hellboy figure. See, I don't always redraw everything!
