Four hardcover books signed by American Secretaries of State, including: Cordell Hull (The Memoirs of Cordell Hull, inscribed inside Vol. I); Dean Acheson (Present at the Creation: My Years in the State Department); and Henry Kissinger (two versions of White House Years: a trade edition and a limited edition, numbered 2404/3500). In overall very good to fine condition, with some minor foxing to the Acheson book.
