A pensioner was stunned to find photographs of the Queen as a teenager on holiday when he was sorting through a relative's belongings.
Ray Fleming spotted the informal pictures in an album belonging to his wife's late uncle Leslie Willoughby while he was clearing out a cupboard.
They were taken by Mr Willoughby when he was working as a saxophonist on board the cruise ship The Empress of Britain in 1939.
The photographs, which offer a rare glimpse of the royal family aware from the glare of the media, show a 13-year-old Princess Elizabeth on deck in summer dress with her younger sister Margaret, father King George VI and mother, then Queen Elizabeth, by her side.
In one frame Princess Elizabeth can be seen grabbing onto her hat as the sea breeze threatens to lift it from her head.
In another King George and his wife can be seen with the Canadian Prime Minister William Lyon Mackenzie King.
When Mr Willoughby's widow Eve died in 1993 all of their possessions were passed to his niece Shirley, now 79, and her husband Ray, 76.
But Mr Fleming only discovered the photographs earlier this year when he was clearing out a cupboard at his home in Wotton, Norfolk.
The retired salesman said he and his wife had no idea Mr Willoughby had mingled with royalty - and they now plan to send the photos to the Queen.
The grandfather-of-five said:
Mr Willoughby, who died from heart failure in 1985, was apparently able to take the photographs after he cheekily approached the royals and asked them if they would mind.
