My grandfather Wallace Paul Cowan (1903-1988) always loved cars, and worked at filling stations as a young man in Springdale, Arkansas. These are some of his photos. I’ve captioned them with what Paul wrote on the back of each.
I think that is Wallace Paul Cowan sitting in the car, and I probably have the paperwork from when he bought it. I’ll update if I find it.
Gasoline was under 25c a gallon, and attendants pumped the gas, checked the oil and cleaned the windshield.
