Thomas M Swem (1848-1931): St. Paul, Minnesota photographer born in Ohio. Operated a studio in St. Paul from 1882-1900. Passed away in Medford, Oregon 1931.

Here's a collection of his cabinet cards at the Minnesota Historical Society. Nearly 100 images without one being a baseball player, mostly portraits of "actual" people including members of fraternal orders, firemen, servicemen, women, families, etc. The ballplayer seems to be a unique image (to view his other cabinets click "see related records") :
