Some Random Beach
??????

I could not locate any existing beach postcard that matches this image, so I enlisted the help of a librarian at the Newberry Library in Chicago, which maintains an archive of the Curt Teich company's records and production files. Within the production file  job jacket envelope there was a photo negative. 

My guess is that somebody wanted a beach scene and the Curt Teich production artist assigned to this job used any beach photo that was available.
