It was sent out as a ‘thank you’ from the Cambridge family over the holidays, and was addressed from each individual family member.
“The Duke and Duchess of Cambridge, Prince George, Princess Charlotte and Prince Louis thank you for your very kind Christmas message,” the card read.
Last year, 11 days before Christmas, they also shared a brand new family portrait.
The photo showed a less formal side to the family, with everyone dressed in casual clothes.
Their Christmas message said: "The Duke and Duchess of Cambridge are pleased to share a new photograph of their family.
The photograph, taken by Matt Porteous, shows The Duke and Duchess with their three children at Anmer Hall. This photograph features on Their Royal Highnesses’ Christmas card this year."
