1-7/16x2-5/8". T206 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. 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. Rube Marquard began his MLB career w/a single pitching appearance for the New York Giants during the final week of the 1908 baseball season. Rube would remain w/the Giants until 1915 when he moved on to Brooklyn in mid-season followed by a stop in Cincinnati before closing out his career with the Boston Braves in 1925. Marquard finished his career w/a record of 201-177 along with a very respectable career ERA of 3.08. Rube was elected to the National Baseball Hall of Fame in 1971. What takes this card to an entirely different level, however, is the fact that it has been boldly signed by Rube and given a perfect "10" signature. The PSA/DNA population report indicates one of only three at this grade level w/only one ever graded higher.
