This image features another typical motel of the first generation of such construction in the 1930s and 1940s. The Steven’s Motel was expanded considerably after original construction.
The description states:

–This structure no longer exists, but the site appears to be still occupied by another motel, run by the Motel 6 national chain. The card likely dates to the 1940s.
