Jody, I for one, do not understand what you are looking for? Can you be more specific? Perhaps a photo that shows the banner you are inquiring about? And/or the Oil Company that displayed the banner?
In the 1940s - 1950s, there were close to 100 different (perhaps more) Oil Company's operating across the U.S. when one counted the Majors and the smaller Independents....
Quite of few of us have banners from different Oil Company's in our Collections; that were used at different Stations... But, do we have the banner you are looking for?
