Throughout board game history, manufacturers made games that attempted to recreate specific popular sports. These games remain popular, though their efforts to duplicate sports achieve varying success. In 1977 Cadaco, maker of other sport-themed games, produced its "Pro Foto-Football" game. A clever two-card system, one for offense, one for defense, makes for each football play. One player's transparent defense card is pulled over top of the other player's offense card. The position of each determines how the play goes.
