I stumbled upon this and thought it pretty cool.
This silent film claims to be, and I have no reason to suggest otherwise, a home movie of the 1929 World Series between the Chicago Cubs and the Philadelphia Athletics, a series the Philadelphia team won four games to one.
The video owner described it as such:
Home movie footage of 1930 Flag Day followed by the 1929 World Series played between the Philadelphia Athletics and the Chicago Cubs. Both games were played at Wrigley field. The World Series was played on either October 8 or October 9, 1929. It includes opening ceremonies, crowd shots, and a few pitches.
