My dad, an Oldsmobile dealer at the time, picked up up the Kaiser Frazer line in the late 40's. I have a Kaiser Frazer service sign from his dealership. I think it's the porcelain metal style, a little over 4' in diameter. It was only used outside for a short time, as I don't think he had the KF line for that long (the best I can remember, as I was pre-school age at the time). It's been stored inside ever since then. It's in mint condition. I have a couple of questions: Any idea what it might be worth, and how would I go about selling it? Any advice would be greatly appreciated.
