Crosley Field in Cincinnati had the distinction of hosting World Series games in both the 1939 and '40 campaigns, and these press pins are from those contests. Both have threaded posts on back and the fronts are in NRMT condition, while the backs have slight tarnishing and stamped maker's marks. The Reds were swept by the New York Yankees in the '39 Classic, but rebounded to win the crown over the Detroit Tigers in 1940, clinching the series at home in Game 7.
