Well-printed back variation for Green-Joyce sportswear stores from the M101-4/5 sets made by Felix Mendelssohn. The photo shows Burt Shotton during his good (and sometimes great) run as St. Louis outfielder. Its SGC VG/EX 4 grade reflects touched corners and light surface toning on front and reverse. M101-4 back variations can prove exceedingly tough, so this is an accessible chance for collectors pursuing them!

M101-4 and M101-5 are sets Mendelssohn created with 200 ballplayers of the mid-1910s. Card backs often featuring ads from a range of stores and companies, no doubt for their own marketing purposes. Contemporary advertising shows some stores giving groups of cards away as an incentive for in-person shopping and others sold their sets by mail order.
