At the time, Charles was only the heir to the British throne and was married to Diana, Princess of Wales.

This card, dated 1987, shows the Prince and Princess with their two children, Princes William and Harry.

Diana is wearing a light-colored jumper with an interesting print and a milky white maxi skirt, her husband Charles is wearing a white striped shirt and black trousers, and brothers William and Harry are wearing white shirts and light blue shorts.

The signature on the card reads: "We wish you a Merry Christmas and a Happy New Year."
