This song celebrates it's 100th anniversary this year. It was written on a New York City train in 1908 when Jack Norworth, an actor, singer and songwriter who had never attended a major league game wrote the words after seeing a sign about an upcoming game at the Polo Grounds. The stamp is based on an 1880 'trade card' . I'm not sure how long they will be available, but we bought a bunch.
