Rare Jackie Robinson double-signed yellow Hall of Fame postcard. PSA has encapsulated the card and certified each signature as Authentic. As most collectors know, when asked to sign his yellow Hall of Fame postcard, Robinson almost always signed on the reverse because the front was slick and not conducive to ballpoint ink. Here, probably at the special request of the recipient, he also signed the front along the top border. Both signatures have been scripted in blue ink, with the front signature grading 7/10 and the reverse signature (which includes the salutation "Best Wishes") grading 9.5/10. Near Mint condition.
