The Smithsonian National Postal Museum has profiled a wide swath of American life on stamps over the years, and this latest online exhibit from their busy minds looks at American sports and athletes on stamps. The collection was created by Alexander Haimann, and it features dozens of unique and compelling stamps, including the 3-cent stamp issued to commemorate the 100th anniversary of the creation of baseball by Abner Doubleday in Cooperstown, New York. Each page of the site has a different thematic focus, including "Take Me Out to the Ball Game" (featuring notable ballparks) and "American Boxing: From Dempsey to Marciano". There is complete information for each stamp, including material on when the stamp was issued. Also, visitors can zoom in and out on each stamp to look for creative details.
