Well, it's pretty clearly Babe rounding the plate. There's not much of an argument on that one.

The guy telling Meusel or Gehrig to slide is Tony Lazzeri. His skin color and body type is identical to Lazzeri's, as well as his height in comparison to Ruth. It's possible it's Meusel, but the guy on deck doesn't look a thing like him, so I highly doubt it.

In regards to the guy on deck being Gehrig, no way- while I see the resemblance, whoever is on deck is telling the runner coming in to slide. Since Gehrig batted after Ruth and Gehrig can't be in two places at once, Gehrig's out of the question.
