Christmas cards signed by Britain's royal family were sold at an auction Tuesday. The cards, that fetched a total of 5,500 pounds ($10,400), included photo cards signed by Prince Charles and the late Princess Diana.

Cottees auction house in Wareham, in the south-western county of Dorset, said 13 cards sent by Queen Elizabeth, Prince Philip and the late Queen Mother to the King and Queen of Greece in the late 1970s and early 1980s, were purchased by a London collector.

But the attention was caught by a separate bidder who snapped up two cards signed by Diana and Charles for a total of 1,595 pounds ($3,052).

One shows a photograph of their wedding in July, 1981, and the other a picture of the couple with their oldest son, Prince William, now aged 24.

Princess Diana died in a car crash in Paris in August, 1997, and Prince Charles married his long-term lover, Camilla Parker Bowles, in April, 2005.

Commenting on the public's apparent continued fascination with Diana, auctioneer John Condie said: "I don't know what it is. There is still that Diana enigma. People do still seem to be fascinated by her."
