Antique boxer photos Richie Mitchell
 

Not being a boxing or photo collector I would appreciate any info you could give me on this piece. The frame measures 10 inches by 27 1/2 inches and is original to the piece with a piece of hard board for the backing. The photos are of boxer Richie Mitchell and are Kohler Milwaukee with the one on far left being embossed with Kohler and having a postcard back. The other four have his boxing record on the back from the 1912-13 season. I have been able to find any matches to these photos anywhere. Also could you help me with approx. value as I will be selling the item. Any help is appreciated.
