Clear, well-printed back variation for Famous and Barr boyswear stores from the M101-4/5 sets made by Felix Mendelssohn. The photo should show a young Roger Peckinpaugh, future MVP shortstop for the Yankees. The block letter ""P"" on his jersey, which Roger never wore, instead matches deadball slugger Gavy Cravath during his days with Philly! While it's by no means the only photo mistake from this era, it's rare to swap two players who went on to such significant careers.

The SGC FAIR 1.5 grade reflects rounded corners and creasing, typical of handling wear from that era. M101-4 back variations can prove exceedingly tough, so this is an accessible chance for collectors pursuing them! The combined SGC/PSA population reports show just three examples graded.

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.
