There has been so much "decorator" gas/oil small sign sh-t produced since the late 1960's. Some of it was made for a short time...some of it longer. Some of these resurface more often than others these days. But, just because an example is seldom-seen in today's marketplace isn't a reason to think it could be real.
After seeing the logo work on the signs for the other gas and oil brands....I'll echo what has already been stated by quite a few others here. These signs are undoubted reproduction, decorator pieces. I have no idea why borntoolate keeps insisting he's sure these are NOT repo's. Perhaps we should simply stop trying to convince him. John
