Found a large photo need help dating it.
 

Here is what I know. I found this photo in Deadwood SD. It was part of an estate of a gentleman that worked for the homestake mine. I've been told that the photo may have hung in one of the bars for years. its a 16" x 20" photo.

The men have base ball gloves and hats. Not sure if was a copy team , exhibition or whatever, St. Paul minn would be close as there were several boxing images with this if Mike Gibbons from 1910'ish.

Any dates, timeframe, assistance feedback would be great.

circa 1900

I would say 1895-1900.
