New Princess Diana photo emerges on 'Antiques Roadshow'
The picture was brought to the show by a former assistant to society photographer Lord Snowden, reports the Daily Telegraph.
"It really is fantastic. It's an odd one, because the boys are dressed in sort of country casuals and don't have any shoes on, and their nanny has not given them any socks as far as I can see," said appraisal expert Clive Farahar. ""But the Princess of Wales is dressed up to kill!"
Farahar valued the photo at approximately $800.
Diana died in 1997 after the car she was in crashed in a Paris tunnel.
