35th President. Highly uncommon typed letter signed (TLS) "John Kennedy" with JFK adding "Good luck!" in his hand beneath his signature, November 2, 1962, 7x9, The White House Washington stationery, sent to Homer E. Facto, a machinist on PT-59, which was commanded by Kennedy after PT-109 was sunk, in full:

I enjoyed hearing from you and I was glad to learn that you are getting along so well. I appreciate your generous comments concerning my activities - I am extremely grateful to you. Hoping to see you sometime soon and with kind personal regards.

The very day JFK sent this letter to his former PT-59 crew member, he made his first address to the nation since announcing the naval blockade of Cuba just 11 days earlier, saying "on the basis of yesterday's aeriel photographs...as well as other indications...the Soviet missile bases in Cuba are being dismantled, their missiles and related equipment are being crated, and the fixed installations at these sites are being destroyed."  The "comments concerning my activities" certainly references Kennedy's actions during the Cuban Missile Crisis.

Furthermore, according to the JFK Library's New York Times Chronology of November 3:

President Kennedy reported to the nation last night that "progress is now being made toward the restoration of peace in the Caribbean" with the dismantling of Soviet missile bases in Cuba. In a brief radio-TV speech from the White House, he said the dismantling had been verified by aerial photographs and other indications. The President declared the United States would "follow closely the completion of this work through a variety of means, including aerial surveillance, until such time as an equally satisfactory international means of verification is effected." But there were no signs that any accord on such verification on Cuban soil was in prospect.

Also of note, Kennedy added a two-word postscript in his own hand, a highly uncommon practice on his Presidential letters.

Letter is in fine condition with light soiling, accompanied by original White House mailing envelope
