Clear, well-printed back variation for H. Weil Baking Co. from the M101-4/5 sets made by Felix Mendelssohn. The photo shows Al "Bruno" Betzel, an everyday infielder for several seasons in St. Louis before he moved to decades as manager in the minor leagues. Its SGC GOOD 2 grade reflects rounded corners, a crease along the top edge, and surface toning. 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.
