I was at the auction last month where he got the AC sign for 225. It is real. His expectations of value are not.
This seller continually buys fake garbage and lists it as real. See current listings of "Sunbeam" clock, "Bear Springs" clock, "Pabst" clock, "Socony" thermometer, Vasser College sign, and Michelin Man statue- all phony junk. Naive? Maybe. Fraudulent- yes. Report him to ebay.
Looking for photos, etc from 60s era Shell-A-Rama gas station and Pal's Diner, Rt. 17 Mahwah, NJ
& US or state highway signs, shields, route markers
