The annual note shows the royal couple and their children, George and Charlotte, in a photo taken by Getty photographer Chris Jackson.
The picture was captured at a party for military families in Victoria, British Columbia, during the family’s Canadian tour, and it shows the four royals looking at a performer as he makes balloon animals.
The moment captured in the photo was part of a fun afternoon tea-party event that the two children enjoyed on the Canadian tour.
A lovely royal surprise arrived today! This photo taken by Arthur Edwards in Victoria, BC was used as The #Cambridges' Christmas / thank you card. Absolutely adore George & Charlotte! #royalmail #postcard #PrinceWilliam #DukeofCambridge #DuchessofCambridge #Kate #PrinceGeorge #PrincessCharlotte #KensingtonPalace #igerslondon #twitter
They got the chance to enjoy a petting zoo, a puppet show, a guitar player and refreshments.
Last year, the couple opted for an outdoor picture of the family-of-four taken during a ski vacation in the French Alps.
