The ad is from the December 1961 Southern Bell phonebook, and looking at the Service Station section is rather interesting. It almost appears that most every station choosing to get a picture ad used the same studio, with each ad having a Zip-A-Tone gray-wash area and a (different) little cartoon service-man.
I'm not completely sure that this building was DuBose. The older phonebooks are less
anal conscientious about giving full numbered street adresses than the current ones. I am sure it was a Phillips 66, and it is on Covenant Road, so I'm pretty sure it's it.
The station is in Ravenwood just at the intersection of Covenant & Bethel Church Roads, catty-cornered from the old Campbell's Convenience Store and the old Piggly WIggly, directly across from the second location of Forest Lake TV / Ravenwood Pharmacy and next door to the old Sunshine Cleaners. (Heavens, that sentence got more complicated and link-full than I expected -- there's been a lot of turnover in the area!)
I'm a little hazy on exactly when the 66 station closed and what followed it. I think it was the 70s, and I think the building got a bit run-down afterwards. The current tenant, Keith's K & A Automotive spruced it up a good bit and seems to do a very good business there -- I had to wait for a Sunday to get a picture of the place without lots of cars in front of it. I really like the bi-level construction and strong roof-line of the building.
