Phillips 66 Gull Wing "New Look" service stations on Route 66
The "batwing" or "gullwing" Phillips 66's, the "New Look" phase from late 1950's to mid-1960's the company went through.
In the 60's, they were complaints that these (and those of other companies) "swoopy" designs were "eyesores". Response was designs that looked more like residential homes.
Most "single" wing, but many were "double" wing designs. Some had signage poking through the apex of wing, some didnt.
Approx. 3,000 built across the country, so fairly ubiquitous design, NOT easily renovated without tearing down the whole thing, so many may still be around.
Examples below:
A group of enthusiasts for everything today ... including folks trying to find this design still standing (dunno the exact addresses so dunno if they are still standing) in their localities.
Several examples for reference when you will likely see/know of one of the "New Look" designs still around in your area.
