In the early days of the NFL, there was concern whether games played at night would be impossible for both fans and players. In short -- could they see the football? So through the early days of the league up until the early 1950s, a white football was used in night games. Pictured is Cleveland's Mac Speedie carrying the ball in the team's win against the Philadelphia Eagles in 1950.

Turned out that batters couldn't pick up the spin of pitches, and the ball was relegated to novelty status.
