It is old history that the First real drive thru gas station in America was built by Gulf and sold "That Good Gulf" gas in 1913. It was in Pittsburg and was the latest thing around. Previously gas was sold by auto dealers, drug stores, and "convenience stores" along with a variety of other unlikely places in small towns and big towns alike. The earliest gas pumps were called pre-visibles as you could not see what was being pumped in to your car. In the teens the visible gas pump came out and soon became popular as many sellers of fuel sold very contaminated fuel and buyers wanted to see what they put in to their fuel tanks after having to drain them a time or two from buying dirty fuel. Gulf was also the company that pioneered deep water drilling and has made many of the latest oil reservoir finds possible due to their unselfish sharing of deep water drilling technology with other companies in the industry. We owe a big debt to the Gulf Oil Company for their pioneering spirit and innovation and few Americans even know about them. Keep on hunting as there are still a lot of cool signs out their to be found! This particular Gulf Sign is from the 1940s vintage as can be seen by the shaded lines at the bottom of the letters. They also sold "No Nox" gas (higher octane) and a variety of other branding names for their fuel. You can see three styles of Gulf signs at aaaLakeside Storage in Provo and it's all still FREE.
