I have an early Case IH light up dealer sign that I am trying to find the approx. value of. It is 4ft x 8ft and has the pole. The logo part of the sign seems to be a vinyl type material that is in good shape. The outer casing is aluminum I believe. I have not gotten the sign out of the barn to take a picture but I have attached a picture of the type of logo that is on it. Has anyone seen one of these sell or is it too large for the average collector?
