Since most of the world was not invited to Princess Diana and Prince Charles' wedding in 1981, now you can get a taste of what it was like by buying a slice of their wedding cake.
On August 11, a 28-ounce portion of the delicious treat will be up for auction and is expected to go for £500 (nearly $700).
The slice — which is 8 inches by 7 inches — has been stored in a decorative tin for 40 years and has a royal coat of arms in blue, gold and red on it.
The slice was given to Moyra Smith — a member of the Queen Mother's household at Clarence House — who preserved it for all of these years.
Smith even had a label on the lid, which reads: "Handle with Care - Prince Charles & Princess Diane's [sic] Wedding Cake."
"It appears to be in exactly the same good condition, but we advise against eating it," Chris Albury, who works at Gloucestershire's Dominic Winter Auctioneers, said.
Diana and Charles got married on July 29, 1981, but they later split in 1992 and finalized their divorce in 1996.
"The astonishing thing was that they were so incompatible, just so incompatible," her former vocal coach Stewart Pearce — who wrote Diana: The Voice of Change, which was released on June 15 — exclusively told The Royal Observer. "Was she in love with Charles? Absolutely. Was he in love with her? No. I mean, completely incompatible."
"So, the machinery of royalty led him to choose the virgin aristocratic bride, which he did. But then, Diana was so different from anything that Charles had ever experienced before – her emotional vulnerability, the absolute belief in emotional transparency, this was something that he found really irksome, because at that time he was so emotionally withdrawn," he continued. "He was trying to find a way of really living the fullness of his own capacity within the construct of being the heir to the British throne."
