This ad ran in 1936, as the Depression receded and the phone company started to ponder how much business they had lost along the way. It's worth clicking on the ad to see the larger image and read the print.
It's really a wonderfully well-done ad. The woman is very Barbara Stanwyck/Fay Wray, and the art and layout are terrific.
Oh, and take a good look at the phone ... notice anything missing? Apparently, we were still at the "Hello, Central?" stage of technology.
