Just an update: I received an email from John Harper, historian for Chevron/Texaco today. Mr Harper said that he doesn't remember anyone asking about this sign. He also said that he couldn't put a value on it, nor did he offer to buy it. I contacted the seller, but honestly don't expect to hear back from him. I see that the high bid is still in the neighborhood of $13.00. I'm not sure if Mr. Harper has checked out this site, but if he hasn't, I hope he will. I am sure he will enjoy the site, as much as I have, if he does decide to check it out.
