Dairylea Ice Cream Sign/Clock

This is a Dairylea Ice Cream Sign/Clock. I acquired this clock from a friends uncle who used to own a store many many years ago. He ordered this sign/clock, but never displayed it and it has been in storage for many years. Everything works on it and it's nearly in mint condition. The sign is made by Dualite. That's all the info i know about it. I haven't a clue what something like this is worth. If anyone knows, please send me a message. Thank you.
