Wait, there's a Cold Smoke car? I must not get out enough, because I'm only familiar with the old yellow Kettlehouse truck.
But evidently there is a Kettlehouse Cold Smoke car (a Nissan Versa, in fact), and it's designed by Big Bear Sign Company. Big Bear entered the car into the Roland 2011 Creative Awards, which is run by Roland to "recognize extraordinary work by Roland users around the world." The company is a "leader in the sign, graphic arts, fine art, vehicle graphics, UV, photography, engraving and 3D modeling industries."
You can vote for the Cold Smoke car right here. So far, it has a middle-of-the-pack 28 votes.
