in Track & Field News of April 1957 on page 15 you can read:
1956 U.S. Olympic Trials, 16mm, sound, showing every event of this great meet. Half-hour showing time. Rental......
Are there anybody who has this movie on VHS or DVD videos to trade with me:
I've several Olympic Movies on DVD video: 1936, 1948, 1952, 1956, 1960 to trade with and much more videos of the history of track & field.
