Okay, not a motel. A rare example of the Apartment Postcard. It could be a motel, though. It has a pool AND shuffleboard.
I think it might have been pitched at retirees. Just a thought.
The address, 322 West Second St, doesn't come back in Scottsdale, but Tempe. Yet the card says it's within walking distance of downtown Scottsdale. The mystery looked unsolvable, until I got a bright idea. How about . . . googling?
This study of post-war Arizona housing put the location by the Valley Ho, and that was all I needed.
