From Tom Verducci's column, a heads-up..
Back in 1922, the Pathe Brothers Company of Paris developed 9.5 mm film, an inexpensive format that became popular in Europe. Two years later, somebody took a 9.5 mm film camera to Yankee Stadium, then scarcely more than a year old, and shot film of some of the greatest legends in baseball history, who could have been there taking part in some sort of exhibition game: Babe Ruth, Ty Cobb and Walter Johnson. The film may have been part of an instructional series that was distributed in Europe and then essentially forgotten for nearly a century.
MLB Productions recently acquired three minutes of this rare, high-quality footage. The fascinating up-close look of Ruth and Cobb hitting and Johnson pitching will be shown on MLB Tonight Monday at 7 PM on the MLB Network. (Disclosure: I work for MLB Network, though not in 9.5 mm.)
