That's certainly of the vintage of the older Mobil ones I've seen, which have been late 1930's, early 1940's vintage, when the oil companies had aviation grade gasoline pumps or tankers available on airfields, just as they did at marinas, and other outlets selling specific use gasoline, vying for customer business. They wanted you to know Texaco fuel was available on premises and this was one way to show it!
