1.438x2.625". 1909-11 T206 Baseball is called "The Monster" for good reason. It's one of the most widely-collected sets of any era. T206 also contains the single most famous card in the hobby, one recognized even by non-collectors. While most cards are easily obtained, the release has some very scarce options, with 16 back varieties in all, that are led by the nearly-mythical Honus Wagner card.

Hugh Duffy (1866-1954) was an American outfielder and manager in Major League Baseball. He was a player or player-manager for the Chicago White Stockings, Chicago Pirates, Boston Reds, Boston Beaneaters, Milwaukee Brewers and Philadelphia Phillies between 1888 and 1906. He had his best years with the Beaneaters, including the 1894 season, when he set the National League single-season record for batting average (.440), a record that has stood for over a century. He also managed the Chicago White Sox and Boston Red Sox and spent several seasons coaching in collegiate baseball and in the minor leagues. Later in life, he spent many years as a scout for the Red Sox. In 1945, Duffy was elected to the Baseball Hall of Fame.
