I bought a collection of signs and other petroliana a few months back and have managed to research just about all the signs. I have had a hard time finding any info on a couple of signs. I have seen plenty of the metal delco signs with wood back but could find little info on the porcelain vertical sign. Some genius bent this one in half so what's it worth as is? I also can find little info on the value of the Anderson Prichard sign. It is 5 foot sign. Then this rocket shaped service sign which I assume is from Oldsmobile dealership. Anyone ever seen it?
