Very difficult Hall of Famer from the 1916 Mendelsohn-photographed issue featuring the scarce reverse advertising "Green-Joyce Department of Sports." Cards featuring the advertisement of the Columbus-based department store are among the most difficult of all the M101-4/5 backs and while the card does exhibit some condition flaws with a set like this condition takes a backseat to scarcity. The "(MK)" qualifier is related to some blue staining at the bottom corners which we have seen with other examples from the issue; the overall visual appeal remains strong.
