Pretty as a picture, the rare picture of Queen at 13
The Prince of Wales was handed a never-before seen photograph of the Queen as a young princess - and declared: "I'll see if Mama remembers it.''
Heir to the throne Charles received the historic image of his mother during a visit to international development charity, Send a Cow, in Bath.
It was presented to him by the organisation's chief executive Simon Barnes and shows the monarch as Princess Elizabeth, in 1939 - the year she turned 13.
The black and white photograph was one of a set taken by Canadian photographer Lawrence Audrain who was invited to Windsor Castle by King George VI and Queen Elizabeth ahead of an overseas tour.
But the image was rejected for publication by the then Queen, who later became the Queen Mother, for being too informal.
It was found in an attic many years after the photographer's death and later gifted to Mr Barnes by the photographer's daughter as a wedding present.
During his tour of the charity, of which he is president, Charles was introduced to Milky May, a life-sized milkable model Holstein cow, but declined the offer to have a go at milking it.
