LOS ANGELES (AP) -- A 33-year-old slice of cake from Prince Charles and Princess Diana's 1981 wedding has sold at auction for $1,375.
The cake, still in its original white and silver presentation box, was sold online Thursday by Nate D. Sanders Auctions of Los Angeles.
With the box was a card stating, "With best wishes from Their Royal Highnesses, the Prince & Princess of Wales."
Auction house spokesman Sam Heller says the buyer is a private collector.
Although the cake came wrapped in its original wax paper, Heller says it wouldn't be a good idea to try to eat it.
He adds, however, that there is a small but dedicated group of royal cake collectors.
Some, Heller says, have purchased cakes dating to the days of Britain's Queen Victoria, who married in 1840.
Today also marks 17 years since Princess Diana was killed in a car crash in Paris.
Princess Diana initially survived the Aug. 31, 1997 limousine crash, but later died from her injuries. Egyptian film producer Dodi Al-Fayed and the driver were also killed. A bodyguard was seriously injured.
French authorities investigating the crash found the driver had a high level of alcohol in his system when the crash happened. The paparazzi trailing Princess Diana was also scrutinized.
Thousands turned up for her funeral held at Westminister Abbey.
Born Lady Diana Spencer, she became the Princess of Wales when she married Prince Charles in 1981. They had two children - Princes William and Harry - before they divorced in 1996.
