Coca Cola Mirror Clock 1976

An Interesting Clock, It is marked in the Screen Printing as 1976, the movement is typical 1960's Junghans Electro Mechanical battery operated, the hands are Spade Style and with the (usual for the era) Centre Seconds Sweep Hand, It stands 20" tall x 11 1/2" wide. I know there must have been many of these made as promotional items but I have had difficulty finding any more.
