Hi Joe,
I agree with you as stated above... I also like the guy holding the ball with his arms crossed.
I was thinking 1870s... I am quite preturbed with myself, because as I stated above this I one of my favorite pics of all time and now I cannot find the full size scan of the stereoview (It was a double shot of the same picture). I had both the front and the back??
The image you see above is where I enlarged, cropped and added a border.
I will keep looking?
