The most recent snap for 2018 showed the Duke and Duchess facing each other while sitting on a bench, presumably at one of the royal properties.
“Wishing you a very Happy Christmas and New Year,” the accompanying caption stated.
In another photo, which was used on the 2017 Christmas card, the couple are seen at the Duchess of Cornwall’s 70th birthday party at Highgrove.
Another delightful Christmas card snap, which shows Charles and Camilla cosying up together, was taken in Scotland during their summer holiday.
The 2013 Christmas card features an equally lovely photo of Charles and Camilla as they watch horses parading on the second day of Royal Ascot.
A final snap shows Charles and Camilla taking part in the Thames River Pageant, which marked the 60th anniversary of the accession of Queen Elizabeth II in 2012.
