IIRC, there is footage or at least photographs of Merkle’s Boner in the Ken Burns Baseball series.
I would have to think that there was no original footage of Merkle’s Boner, since it was 1908. Any motion picture had to be a recreation. As for a photograph, there were probably photos of the game but it would have been an incredible stroke of luck to get any of the event itself. Sports action photography was still in its infancy.
And I want this part of the thread to continue as long as possible because I don’t think I will have the chance to type “Merkle’s Boner” this many times ever again.
