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.

John Dwight Chesbro (1874-1931) was an American professional baseball pitcher. Nicknamed "Happy Jack", Chesbro played for the Pittsburgh Pirates (1899-1902), the New York Highlanders (1903-1909), and the Boston Red Sox (1909) of Major League Baseball (MLB). Chesbro finished his career with a 198-132 win-loss record, a 2.68 earned run average, and 1,265 strikeouts. His 41 wins during the 1904 season remains an American League record. Though some pitchers have won more games in some seasons prior to 1901, historians marking 1901 as the beginning of 'modern-era' major league baseball refer to and credit Jack Chesbro and his 1904 win-total as the modern era major league record and its holder. Some view Chesbro's 41 wins in a season as an unbreakable record. Chesbro was elected to the National Baseball Hall of Fame in 1946 by the Veterans Committee, though he had received little consideration from the Baseball Writers' Association of America (BBWAA). Some baseball historians consider the 1946 election a mistake, and believe that Chesbro was elected solely on the basis of his 1904 season.
