CHICAGO (AP) — The Illinois High School Association says they’ve discovered some of the earliest high school basketball film footage around. The film shows action from IHSA state basketball finals from 1932 to 1936. It was an era when high school basketball players in Illinois had no numbers on their jerseys and when there was no center line. Rules required a jump ball each time a team scored. The games would appear unconventional in some ways to basketball fans today. That includes no center line. The footage also shows players frequently making near half-court shots. A Wednesday press release says IHSA historian Scott Johnson discovered the footage in the personal collection of a former IHSA administrator, H.V. Porter. He died in 1975. The IHSA video is available on YouTube.
