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.

Michael Joseph "Mickey" Doolin (May 7, 1880 in Ashland, Pennsylvania - November 1, 1951 in Orlando, Florida), was a professional baseball player who played shortstop in the Major Leagues from 1905 to 1918. During his career, he played for the Philadelphia Phillies, Baltimore Terrapins, Chicago Whales, Chicago Cubs, New York Giants, and Brooklyn Robins. His name is often misspelled as "Doolan" due to many of his baseball cards being misspelled.
