A piece of American history! A handwritten letter penned by Jackie Kennedy to her husband, John F. Kennedy, in 1957 or 1958 is hitting the auction block. According to Boston-based RR Auction, the three-page letter — sent while the First Lady was away from home on a trip — is thought to be “the only Jackie love letter to Jack [to] ever be offered at auction” and the note previously sold for more than $22,000 in 2016.

In the note, signed “All my love, Jackie,” the socialite told her husband that she was finding it difficult to communicate with him and was seemingly worried about the success of their marriage. “I think it is usually good when we go away from each other as we both realize so much. We are so different — but I was thinking this trip — that every other time I’ve been away, you would write ‘don’t ponder our relationship too much’ etc,” Jackie penned.

After asking about the couple’s young daughter, Caroline Kennedy, and referring to the child as “a baby we both love,” Jackie added, “You are an atypical husband — increasingly so in one way or another every year since we’ve been married — so you mustn’t be surprised to have an atypical wife. Each of us would have been so lonely with the normal kind. I can’t write down what I feel for you, but I will show you when I am with you — and I think you must know.”

Regarding the rare note, Executive VP at RR Auction, Bobby Livingston, said in a statement, “Jackie Kennedy was a prolific writer and we have seen dozens of letters to friends and family —  but this is the only letter we have seen where she speaking directly to Jack about their relationship.”

The RR Auction sale of Jackie and JFK’s personal belongings also includes a collection of photos of a teenage Jacqueline Bouvier believed to be taken at The Homestead in Hot Springs, VA during the summer of 1945. “These marvelous never-before-seen snapshots wonderfully portray Jackie’s entering young womanhood at age 16,” Livingston said of the pictures.
