Typed souvenir presidential resignation, one page, 5.25 x 8, on mock White House letterhead, dated August 9, 1974 but signed later on. Addressed to Henry Kissinger, in full: 'Dear Mr. Secretary: I hereby resign the office of President of the United States.' Signed boldly in black ink at the conclusion. In fine condition.
