Pitching Machine Photo Question.
 

:confused:I bought several baseball news photos and there was a photo that looked like a negative of the other photo. Can anyone tell me if there is a reason for the dark photo? Thanks! D.

It's an oddity all right. It could be a proof, which would mean it was a test of some sort before the final photo. They had proofs with photos, just like they had proofs with T206s.

Here are two from Baseball Magazine.
