I picked up this Texaco No Smoking Sign up today on eBay. It has the Circle R (registration) instead of the earlier Reg. T M registration marking. It does not have a date or made in USA markings. My questions are what would be the probable date? And secondly does the sign look authentic to our veterans. It looks right to me but I am putting on my big boy pants and getting ready for the bad news if it does come. What do you guys and girls think?
