Dear Oldgas Veterans,
I need your help. I purchased this Union 76 porcelain curved signed. It appears original...I believe circa late 60s early 70s. Here is my question: How was this curved sign used? I did some research and found a pic of a Union 76 gas station pump (pic number 3) where they appear to have some sort of images used around the curvature of the top of the gas pump. Was this the manner that this sign might have been used? Can anyone confirm this?
Thanks in advance!
