M101-4/5 are sharp black-and-white sets that publisher Felix Mendelssohn created from 200 select ballplayer photos of the mid-1910s. Card backs can advertise a range of stores and companies and The Sporting News appeared on so many that their name became shorthand for many M101-4/5 cards, even blank backs.

This actual TSN back for Black Sox star Chick Gandil, graded CGC GOOD 2, shows honest wear all around, with sloped corners, a surface mark at upper right, and modest toning on the back. The Black Sox scandal has fascinated collectors for over a century and this shows their first baseman as clearly as any contemporary source. It's a highly presentable and accessible slice of complicated history that would suit many collections.
