Presented is a wonderful collectible: Babe Ruth's signature on a special first day commemorative postal envelope issued from Cooperstown, New York on the day of the opening of the Baseball Hall of Fame. June 12, 1939. The initial vote for Hall of Fame membership took place in 1936 - Ruth had played his last season in 1935, finishing his careeer with the National League's Boston Braves, and 170 of the 226 possible votes were needed for election. Ty Cobb led the voting with 222 votes, and Ruth and Honus Wagner received the next most votes with 215 each. Also comprising the initial class voted into the Hall of Fame were pitchers Walter Johnson and Christy Mathewson. Although the aforementioned five players were elected to the Hall of Fame in February of 1936, they were not formally inducted until the Hall of Fame officially opened on June 12, 1939. By the official opening of the Hall of Fame, then called the National Baseball Museum, 26 persons had been elected and all 11 living members were present on June 12th, although Ty Cobb, because of a train delay, was late. The offered signed 4.6" x 6.5" envelope was postmarked on June 12, 1939, at 9 a.m. in Cooperstown. On the envelope is a 3-cent special baseball stamp (showing a vintage baseball game), and underneath the postal stamp, the cancellation stamp reads, "FIRST DAY OF ISSUE". The envelope is addressed to Peter M. Busceauer [?] in the Bronx, N.Y. On the left front of the envelope is written "IN COMMORATION OF THE ONE HUNDRETH ANNIVERSARY OF ORGANIZED BASEBALL", as well as an image of a vintage player pitching underhanded. The empty envelope is still partially sealed. Ruth signed the outside of the envelope in blue ink from a fountain pen. His big and bold signature is neatly written. The signed Ruth envelope comes with a PSA Letter of Authenticity.
