President John F. Kennedy's official United States senate card with his Jack Kennedy signature. The card was found stuck in the pages of his book, The Strategy of Peace published in 1960 when he was still in his term in the senate - preceding his election to the Presidency in November. The card is in excellent shape as you can see from the photos. The hardback book (with the book jacket) is also in excellent condition considering it is now 59 years old. The book is being sold with the ...card. This will be an excellent historical memento on the eve of President Kennedy's assassination this month.
