A popular collecting niche for Roadside America postcards is gas stations.
Here's a particularly nice one, the Lower Dells Filling Station, Wisconsin Dells, WI linen postcard, sporting a Phillips 66 sign.
The caption on the reverse boasts "superior service with courteous attendants at your command".
I drove past the Dells a few weeks back, but I didn't spot anything approaching this level of service or architectural aesthetic.
