Prince Charles and Camilla: How love finally triumphed
The photograph, taken by Stephen Lock in June, shows Charles and Camilla sharing a joke while attending Royal Ascot.
The smiling Duchess is dressed in an elegant Anna Valentine pansy print chiffon dress with a peppermint green silk coat, and holding a silk clutch bag, by the same designer.
Her husband, pictured as he turns to face Camilla, looks smart in an Anderson and Sheppard morning coat, a shirt by Turnbull and Asser and a top hat by Lock & Co.
Printed on the cover of each Christmas card is the Prince's feathers and the Duchess' official cipher. Inside the card, opposite the photograph, is written the message, "Wishing you a very Happy Christmas and New Year".
