This guy sells Gulf and Texaco and others signs every week with the same patterns and patina. Maybe I am wrong here, but he sure has a lot of the same style of signs judging by previous sales. Here is a link to one of his auctions.

These signs seem to have heavier shelving than those made here in the USA from Standard Sign of Ohio. They may not be dated but what's the difference than the ones on Ebay with the small dated ones that can be easily chipped off and rusted like these signs. Dated signs don't seem to be the answer.
