2 1920s football games (Yankee Stadium, Army-Navy Polo Grounds)
The football game at Yankee Stadium is: 11/12/1927 Army 18 – Notre Dame 0 80,000 attendance
The Polo Grounds footage was taken no earlier than 1924. You can see a shot of the CenterField clubhouse and grandstand, which was added in ’23-’24….these were proly taken between 24-27.”
According to Wikipedia, Army-Navy games were played at the Polo grounds in 1913, 1915, 1916, 1919-21, 1923, 1925 and 1927 so I would think it was one (or more) of those years.
You’ll see some football, the crowds, marching bands at half-time, the Army mule and the Navy mascot, a goat, and cheerleaders. The sign you see at :21 says “Please remain seated until the cadets march off, when game is over.”
