I find myself in possession of 5 of these identical signs. Roughly 12 x 2 inches. I can't find any info on them and what they are worth. I took them to a pawn shop and they couldn't find anything either. They were sitting in my grandfather's shed probably since the 70's. I don't really know for sure. I would appreciate it if anyone had any info on them and info on what they are worth. Thanks.
