New York City once had three major league teams: the New York Yankees, the Brooklyn Dodgers, and the New York Giants. Fourteen World Series match-ups have pitted New York City teams against one another, and the famed Yankees have won the World Series 27 times. When a New Yorker (James Farley) became Postmaster General, he approved the issuance of the first baseball stamp in 1939 commemorating the baseball centennial.
