The Baby Zep.
What is this Centennial of Baseball you speak of? Everyone knows that baseball was played in southern Ontario at least a full year before Abner Doubleday "invented" it.

In 1988 Canada issued a stamp which challenges the United States claim to have originated the game. It celebrates the 150th year of Canadian ball (putting it a year ahead of our legendary 1839 US date). The claim is based on a letter to Philadelphia's Sporting Life describing a game played in Beachville, Ontario, 4 June 1838.
