Picture Showing 9-Year-Old Prince Charles While Listening To His Mother Made Public

London, England (BANG) - A photograph of Britain's Prince Charles aged nine listening to his mother, Queen Elizabeth, give her first Christmas TV broadcast has been made public for the first time.

The exclusive shot of Charles from Christmas Day 1957 - which sees him sitting in a chair wearing sound engineer earphones - was taken by the BBC's superintendent of lighting Harold Mayhew, nicknamed "Mr Grumps" by BBC staff, and have now been made public by Harold's son Eddie Harper-Mayhew.

Eddie, who also has photographs of Charles and Princess Anne looking through an old-fashioned TV camera, revealed the collection on BBC TV show "Antiques Roadshow" over the weekend.

He said: "They have never been published and this is the first time they have been seen, although I have a feeling the royal family has a set."

However, despite being told by antiques expert Paul Atterbury that the collection could fetch between $2,200 and $3,000 if it was sold, Eddie insisted he will never part with it.
