The game's creator, David W. Knapp, was an inventor who marketed battery operated games. It was made during a period of time in which the public was fascinated with the concepts of electricity and communications.

The box lid features a picture of the then communication towers at night. The lid is hinged to the box bottom, and the inside of the lid not only features information about the game and the battery, but also includes the Morse and Continental Telegraph Codes.

Good question! I think you can use any battery that fits, looks like a D cell, not sure. I think it needs some kind of container for the battery... I found a picture of the battery here (scroll through the pics).
