Three ALSs signed “Jackie,” each penned on light blue 5.75 x 7.75 sheets of 1040 Fifth Avenue letterhead, none dated. The three ‘thank you’ letters are addressed to “Tish,” Kennedy’s former White House social secretary, Letitia Baldrige. One letter reads: “Thank you for your sweet inscription in your marvelous book—I adore it and really do laugh so much every time I open it—You are really special and how lucky I am to have known you.” Another, in part: “Only you would have a letter waiting—when I got back from the Library—You are right—it was so moving and emotionally draining. I was surprised at how shaky I felt. To find your letter was like having a hand to hold.” In overall very good to fine condition, with irregular toning to one of the letters.
