The Grid-Graph board measured 15 feet by 12 feet and featured a glass replica of a football field. The team names, score, and number of downs were listed across the top, and player names along the sides. Below that were the various plays, like punt, interception, or touchdown. Operating the board was a multi-person production. One man made transcripts of the Morse code coverage coming in by telegraph, and then another relayed these as instructions to those controlling the lights. A switchboard operator lit up a bulb next to the play being made and the players involved. Meanwhile, a final man moved a free-standing bulb behind the glass to represent the ball’s position on the field. Of course, he only knew the yard markings and not the ball’s exact spot, so some artistic flourishes were allowed to create drama and suspense.

“That crowd came out of those swaying stands and across the floor bent on getting some souvenirs of the game from the board. We had to rush out in front and fend them off or the whole thing would have caved in on us all. They tore out the players’ names and got a few lights, but we saved the board.”
Although the board survived that trial, it would not survive dwindling attendance and funds over the following decade. In 1941, the Grid-Graph was quietly put to rest.
