Clear, well-printed back variation for Morehead Baking Co. from the M101-4/5 sets made by Felix Mendelssohn. The photo shows infielder Zinn Beck in the St. Louis kit where he spent the bulk of his career. Its PSA EX 5 grade reflects touched corners and slight print tilt. M101-4 back variations can prove exceedingly tough, so this is an accessible chance for collectors pursuing them! The population report shows this as the highest of just two graded for Morehouse Baking #12.

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.
