That's a cool rack. I sold a neat Carter's Carburetor sign, with a bracket, in Columbus last year but can't find a picture of it to save my life. It was about 12"x30". I usually take pics of everything!! It would look great above that rack.
Here's a picture of the same sign and original bracket (found on the internet) that I sold.
Thanks Speedracer, I actually have the sign and this display for carter carbs. Now I have to figure out a place to display them together, not looking forward to the change reaction that it will cause.
