Having lived on 24th and St. Louis back in the 50s, I don't recall a gas station on 28th, but I may have not biked around that area much (no friends or parks near) or paid much attention if I did. It was kinda odd to see a gas station on a side street, but I know they existed. Taverns and grocery stores, yes. Gas stations, not so much.
The Sunoco service station on 27th and Lawndale:
