A slice of Princess Diana and Prince Charles' royal wedding cake, which was recently put to auction, has been sold for a whopping $1,375.

The piece of fruit cake was put on auction at the Nate D Sanders monthly auctions held in Los Angeles on December 17. Bidding for the slice of cake described by the auction house as "classic British fruitcake with cream cheese frosting" began at $1100.

The cake, which was made by David Avery, head baker of the Naval Armed Forces, was wrapped in its original wax paper and doily in a box. A gift card accompanied the box that read 'With best wishes from Their Royal Highnesses, The Prince & Princess of Wales'.

What's interesting is the fact that despite being over 34 years old, the cake is still edible having been preserved by its high alcohol content, Hello magazine reported.

"The wedding of Lady Diana and Prince Charles captured the attention of the world on television and through many newspapers and magazines," said auctioneer Sam Heller, reported PageSix. "And even today, people just cannot get enough of the late Princess."

"Alcohol has preserved the cake making it still edible, although collectors would rather it remain intact. Collectors are willing to pay a premium to own a piece of history from the most famous wedding of the 20th century."

Princess Diana and Prince Charles' royal wedding reception was held on July 29, 1981 at Buckingham Palace after the Church of England ceremony at St. Paul's Cathedral. The reception was attended by 120 guests. In September, a collection of 12 never-before-seen photos from Princess Diana and Prince Charles' wedding event was sold for over $12,000.

Also put on Thursday online auction was a White House rocking chair used by late U.S. President John F. Kennedy. The wooden chair was put on sale with a starting price of $70,000.
