Ferguson Sign

Hi, I found a Ferguson Tractor double-sided sign approximately 12 feet tall, do you know its value? April 28, 2014.

I’m not sure how much the sign is worth. Can you provide some additional information? Is the sign itself 12′ tall? Is this a painted sign, or porcelain. Is it neon or does it have any sort of lighting attached to it. Lighted versions of these signs usually include a power supply or transformer. What is the condition of the sign? I’ve seen new old stock Ford Ferguson neon signs sell for as much as a new one and sometimes more.
