Marilyn Monroe isn't the only blonde beauty to have caught John F Kennedy's eye. 

The president had an affair with Swedish aristocrat Gunilla von Post while he was married to Jacqueline Bouvier, and their love letters are now going up for auction. 

Doyle New York estimates that the set of letters will sell for $10,000 to $15,000 when they are auctioned off Monday.

Kennedy was a 35-year-old senator just three weeks away from marriage in the summer of 1953, when he met 21-year-old von Post on a trip to Cannes, France.

Kennedy was a 35-year-old senator in 1953 when he met von Post, 21, in France three weeks before his marriage to Jacqueline Bouvier (the Kennedys on their wedding day in September 1953, right)

They spent one evening together in which, she recalled in her memoir: 'He turned and kissed me tenderly and my breath was taken away.

'The brightness of the moon and stars made his eyes appear bluer than the ocean beneath us.

For the next three years, the two exchanged letters back and forth across the Atlantic, with Kennedy even planning to leave his wife for the von Post, according to her 1997 memoir 'Love, Jack'. 

The letters going on auction this week are the second batch of love letters found in von Post's estate, following her death in 2011 at the age of 79.  The previous collection sold for $115,000 in 2010. 

Doyle New York expects the letters - many of them written on U.S. Senate stationary - will fetch between $10,000 to $15,000

The earliest letter included in this batch is from a year after the two met, and in it Kennedy asks to meet up with von Post on an upcoming trip to Stockholm. 

'Is there any chance you shall be there as I would like to say hello,' Kennedy wrote. 

However, that trip was cancelled when Kennedy underwent spinal surgery. 

He tries to organize a get-together again a year later, saying: 'I am anxious to see you - is it not strange after all these months? Perhaps at first it shall be a little difficult as we shall be strangers - but not strangers . . . It is a long way to Gunilla - it is worth it.'

The following letter starts with Kennedy saying von Post 'looked well and happy' in a photo she sent of him and his plans for an upcoming trip to Sweden. 

The two reportedly spent a week together in 1955, according to von Post's memoir. 

Von Post wrote of the affair: 'I was relatively inexperienced, and Jack’s tenderness was a revelation. He said, "Gunilla, we’ve waited two years for this. It seems almost too good to be true, and I want to make you happy".'

'If you don’t marry come over as I should like to see you,' Kennedy's final reads. 'I had a wonderful time last summer with you. It is a bright memory of my life - you are wonderful and I miss you.'

The two were reunited only once more, by accident at a gala at the Waldorf Astoria hotel in New York in 1958. By then, von Post with pregnant and Kennedy was just three years away from the White House

At the benefit, von Post scribbled a note to Kennedy and had a waiter pass it along to the senator, who then signaled to meet him the in corridor.  

'He just gave me a huge hug. And then he said "It’s wonderful to see you. I love you".' She said 'it was lovely.'

Von Post's first husband Anders Ekman died in an accident, and she later moved to America after marrying Weisner Miller, an American IBM executive. 

That marriage ended in divorce, but she continued to live in Florida.
