Handwritten letter signed "Jackie Robinson," one page, 7.25 x 10.5, personal letterhead, no date but postmarked December 22, 1951. Letter to Mort Shaw of Brooklyn, in full: "I may have written you before about the letter you wrote Miss Day. I can say it was so well done and I only wish I had fans such as you that when you felt they were wrong would write letters just as the one you wrote. We in public life need reminders such as yours and I assure you that type of letter is more effective. Incidentally I was very much impressed with your ideas on the injuries. I would appreciate it if you felt I need some advice to write because I believe we owe all our success to the public and have a responsibility to you." In excellent overall condition. Accompanied by the original mailing envelope addressed in Robinson's hand. Robinson is very scarce in autograph letters dating to his legendary playing career with the Brooklyn Dodgers. After a heartbreaking 1951 season, Robinson would lead the Dodgers to the National League pennant in 1952. Robinson had broken baseball's color barrier only four years earlier in 1947, tactfully dealing with insults and epithets hurled at him by a prejudiced public. This letter demonstrates the humility and grace that made Robinson successful in his "public life" on and off the field. Pre-certified PSA/DNA.
