Toned and well used Reach American League baseball which has been signed by Chicago White Sox Hall of Fame pitcher Ed Walsh and Chicago Cubs Hall of Fame pitcher Mordecai 'Three Finger" Brown. The Walsh signature rates 3 out of 10 on side panel with Brown displaying as 4 out of 10 on opposite panel. Period fountain pen inscription in unknown hand is found on an adjacent panel of the ball, "Final Ball Sox Win". The 1906 World Series was a regional contest between the North Siders (Cubs) and the South Siders (White Sox) in which the Sox prevailed in a six game affair. The sixth and final game was captured by the White Sox by a score of 8-3 on their home field to which the offered baseball saw game action. The baseball was originally de-accessioned from the Helms Museum in Los Angeles and believed to have been part of a larger donation from famed actor and pioneering collector Joe E. Brown. The rarity of documented World Series game baseballs from the early 1900s period bears noteworthy attention. The added corroborative presence of Brown and Walsh signatures place this example among the very finest of that small surviving population.
