Wilson Official American Association baseball has been signed across the sweet spot, "Afectuosamente, Martin Dihigo Llamos." side panel displays fully inscribed saturation by Dihigo (roughly translated to read "To My Old Friend" with recipient's name) and "Stadium Tropical, Dec 18 de 1938." Period fountain pen signature rates 7 to 8 out of 10. Ball displays mild even toning with a hint of scattered surface wear mentioned for sake of accuracy retaining generally bold League stampings. As his Hall of Fame plaque notates, "Dihigo was perhaps the most versatile player in baseball history...Playing in the Mexican League in 1938, he went 18-2 and led the league with a 0.90 ERA, while also winning the batting crown with a .387 mark." Only the second Dihigo single signature baseball we have handled in our 34 year company history and is the only playing career era specimen we have documented to exist. Includes full LOA from PSA/DNA (7 NM) and full LOA from JSA: Ball EX, Signature: NM
