The historic Boots Motel in Carthage, Missouri, added a new “Air Conditioned” supplementary sign that’s a faithful re-creation of one that hung from the main sign decades ago, along with the “Radio in Every Room” sign installed last year.
I failed to notice the “Air Conditioned” sign in old postcards of the 1939 motel, which is being restored to its late 1940s to early 1950s heyday. Courtesy of 66Postcards.com, you can see that sign if you look closely.
Here’s a close-up of the sign, where the “Air Conditioned” portion is visible.
Ron Hart of the Route 66 Chamber of Commerce noted in an email:
The electrical conduit was added to the exterior of the building so window units could be installed, and may date back to the 1940s!
