Though John F. Kennedy and Jackie Kennedy were seen as the ideal American couple, the president had several extramarital affairs, including a deep relationship with artist Mary Pinchot Meyer.
In 2016, a love letter Kennedy wrote to Meyer was released before auction, offering a rare glimpse into their private connection.
According to R.R. Auction, Kennedy penned the note in October 1963, just a month before his assassination, but it was never sent.
It remained in the possession of his White House secretary, Evelyn Lincoln, and was later sold at auction for nearly $89,000.
Meyer came from a wealthy family and first met Kennedy at a dance, though they reconnected years later in Washington.
She was also a close friend of Jackie Kennedy before beginning her alleged affair with the president.
Meyer was murdered in 1964, and a diary found after her death reportedly confirmed the relationship, though its contents remain secret.
