Extremely rare official Spalding Tri-County League baseball signed in blue ballpoint on the sweet spot, "George Sisler," with the date on the north panel, "March 9, 1970." In fine condition, with spots of soiling to the lower panel. Accompanied by a full letter of authenticity from PSA/DNA. Sisler is considered rare in single-signed baseballs, and this is the first such example we have ever offered.
