@Stygian Warrior--Bill, I remember it was in the pdf of the mists content. I'm almost perversely hoping that only a picture is available for a while so we can see your conversion concept. Good grief!
P.S. you may be playing in the con this weekend with some of my painted Dwarves, but after that, your horde, unpainted, primed, or painted, is due for a smackdown on our table. Cheers.
@Southpaw--thanks for the tip to Coki's site. I will check out the chariot pics there. I also used a laser printer to get that Empire picture--laminate it and it makes an excellent oversize bookmark.
