Original 16 MM film highlights for the first half defense gameday December 6, 1979; Chicago Bears VS. St. Louis Cardinals. This is an original game day film used by referees to spot and mark various penalties during game day action. This film came from the estate 16of an actual NFL referee, and is a unique piece of football history. Not sure how long this film actually is. It comes in the original bright orange filmstrip cannister, and appears to be in excellent overall condition, although it has not been viewed by us, we do not have the necessary equipment to do so.
