A fresh-faced Princess Diana flashes a smile for the camera as she joins her husband on a shoot.
The candid photograph, taken in the early 1980s, offers a rare, unguarded glimpse at the life of the young princess away from the public eye.
It is one of a handful of never-before seen images of Diana and her new husband, Prince Charles, that have been recently unearthed after apparently spending decades forgotten in a drawer belonging to a former royal housekeeper.
Diana is seen wrapping up in a well-worn Barbour jacket and large silk scarf and sporting a pair of classic green Hunter wellington boots.
Similar attire is sported by the other members of the party, who were photographed warming up with hot drinks as they stopped for a picnic on the side of the road.
The collection of unseen photographs belonged to the late housekeeper of Princess Alexandra, the Queen’s cousin, at her home at Thatched House in Richmond, and were discovered in a drawer following her death.
They will be auctioned at Littleton Auctions in Evesham, Worcesteshire, tomorrow.
The photos have emerged for auction and the auctioneer says it is ‘very difficult’ to estimate their value.
