This lot features an incredibly rare, post-WWII regional strip card artifact showcasing St. Louis Cardinals legendary shortstop and 1944 NL MVP Marty Marion. Cataloged in the American Card Catalog as the R346 Blue Tint series, this minimalist issue features a distinct monochrome blue halftone portrait framed by a simple blue double-border, with card number 3 sitting neatly in the bottom right corner. Left ungraded in raw vintage condition, the blank-backed card displays a heavy, genuine patina, including soft rounded corners, edge chipping from hand-cutting, and surface wear. It offers pre-war and vintage team collectors a fascinating, character-rich puzzle piece representing one of the earliest regional sets printed after the conclusion of World War II.
