ALS, one page, 5 x 7, personal letterhead, January 19, 1972. Response to an autograph request. In full: “You wrote to me last August—telling me how sick you were—and asking for an autographed picture of myself for your son Michael. Forgive me for taking so long—I was away on a trip and only recently was I able to obtain some photographs. Your letter made me very sad. My own father died only a short time ago. I hope all is well with you—and that God has been kind.” In fine condition, with a trivial wrinkle to the lower left corner. Accompanied by the original mailing envelope addressed in Sendak’s hand, including a signature in the return address area. RRAuction COA.
