According to “The Unforgettable Buzz” Electric Football was adapted from a previous game made by Tudor using an electro-magnetic relay device, the vibrating electric horse race game which evolved from Tudor’s 1937 Electric Auto Race.
This is the game made from Patent # 2167985
Recently, I was able to purchase one of these games from an eBay seller located in Lewisburg, TN. Not only was it very rare to find one of these games but also from a seller not far from where I live so that I was able to pick it up locally and save on the shipping cost. This game now resides in the permanent collection of The National ELECTRIC FOOTBALL Game Museum.
