IMO the man holding the suitcase is Mike Finn, Mgr. 2 sources that have player portraits to compare against and/or use process of elimination are
www.arkbaseball.com. I also suggest contacting the administrator of that website, Caleb Hardwick. He will be more than willing to assist you. Also on Amazon in the book Baseball in Little Rock by Terry Turner there is a photo of the 1901 team (Finn was the manager 01-04 and 07-09).
