1-7/16x2-5/8". 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, led by the nearly-mythical Honus Wagner card. McGraw was a third baseman of the pennant-winning 1890s Baltimore Orioles teams and a three time World Series champion as manager of the NY Giants. Inducted into the National Baseball Hall Of Fame in 1937.
