Princess Diana's edible wedding cake set to sell for $4k after 34 years

A 34-year-old slice of fruit cake is set to sell for a staggering $4000- because it is from the wedding of Prince Charles and Princess Diana.

Despite being made 34 years ago, the cake has been perfectly preserved thanks to the high level of alcohol in it and is still edible - but its value comes from the fact that it is still intact.
