When someone mentions WDAY in Fargo, this picture comes to me immediately. After Judy and I finished our first big date, the Fargo South Prom, I took Judy to work at the station. She worked at the desk in the picture.
Every phone in the building connected to that switch board. You can see the lights and a plug for each phone. Even the dial (used to “dial” a telephone number) is obvious, right next to the coffee cup.
