Those prices are kinda high for the era....unless it was in CA. I remember paying prices like that in 1970 around my area but Mobil Supreme was around 36.
Cool - a huge investment! I remember as a kid when stations still had guys uniforms pop out to service the car like the opening of Back to the Future. Check the oil, tires, clean the windows and gas was around 25 cents a gal. A crusty neighbor was always suspicious when having his oil checked telling the attendant saying to him he was a qt low "Is this with our without your thumb?" My future wife, just after our HS days, got her picture in the paper working at our local Clark station pumping gas as back then it was odd to have a female working at a gas station. I had some reservations while buddy's gave me some **** about it having her fill up their old muscle cars back when.
They're wearing ahhh interesting uniforms..what a way to increase biz!
The phirst Phillips station was in Wichita, KS.
