Contract, three pages on two adjoining sheets, 8.5 x 11, February 23, 1921. National League uniform player's contract in which Rogers Hornsby agrees to render "his skilled services during the playing season of 1921" for the St. Louis Cardinals, for a salary of $10,000. Signed at the conclusion by Hornsby and countersigned by St. Louis Cardinals President Sam Breadon. The reverse bears the stamped signature of National League President John A. Heydler. In very good to fine condition, with an archival tape repair to the interior hinge. Hornsby had one of his greatest seasons in 1921, opening up the 'live ball era' with 21 home runs and a Major League-leading .397 batting average, 126 RBI, 235 hits, 44 doubles, and 18 triples—another couple of home runs and he'd have won the Triple Crown! Accompanied by a full letter of authenticity from PSA/DNA.
