This is your moment to own a piece of telephone history and will be the PIÈCE DE RÉSISTANCE of your collection.

This Picturephone system unit was fabricated during an "experimental stage" and it was promoted as the telephone of the future, but high cost, inconvenience and a lack of compatible devices turned it into the phone of dreams instead, so very few were made for public use. They did however set up Picturephone booths in a few large cities with Chicago being one of them. It is my belief, but not documented that this is one of the few that were installed in the Prudential Building downtown Chicago.
