All secret ever becomes clear.

The tradition of sending postcards in the form of a family portrait for Christmas has existed abroad for many years. It is carefully honored and monarchs: every year they congratulate fans on social networks, and also send to relatives, friends and acquaintances by mail. Portraits in either case are usually different . Today, the network has a series of Christmas cards for Princess Diana and Prince Charles with their sons, William and Harry, who would have remained unpublished if it had not been for coincidence.

Their current owner, who wished to remain anonymous, found them when he was sorting out boxes with the belongings of his relatives, Muriel and George Constable, the recipients of the royal postcards. 

We could not even imagine that these cards exist. We found them in a box that previously belonged to Muriel, where she kept her collection of postage stamps. They lay dozens of years. We did not think that they could be worth anything, since we were looking for valuable and rare stamps, but we asked Hansons auctioneers to look at them too. 
As for Muriel and George themselves, they died in 1993 and 2002, respectively, and, most likely, the postcards were intact in the box from the moment Muriel died. They were the parents of my brother’s deceased wife. At one time, George and Muriel ran a post office in Newton Saint Loe, near Bath, in Somerset, a village that is part of Cornwall county. Perhaps that is why they received postcards from the royal family.

There are 6 Christmas cards in total, the earliest of which is dated 1985. They will be auctioned on July 31 at Bishton Hall in Staffordshire. Starting price from 1500 to 2000 pounds for one lot.
