Jackie Robinson Yellow Hall of Fame postcard, signed by Robinson in black ink (grading 9/10). Encapsulated by PSA, with the signature certified as "Authentic." As was his custom when signing yellow Hall of Fame postcards, Robinson has penned his name on the reverse, adding the salutation "Best Wishes" above his signature. The card has been laminated on the front and the reverse displays uneven toning from its having once been mounted and framed. Good condition overall. Full LOA from PSA.
