Slice of Princess Diana and Prince Charles' wedding cake up for auction

After 40 years, Prince Charles and Princess Diana's wedding cake is up for auction. The slice was given to Moyra Smith, who was a member of the Queen Mother's household at Clarence House. 

Preserving it for many years, she kept the cake in the tin and labelled it: "Handle with care Prince Charles & Princess Diane’s (sic) Wedding Cake", dated 29/7/81.
The cake was initially sold to a collector in 2008 but now it's up for auction on August 11. The slice is expected to be sold between $418 and $697. It had a marzipan base and was decorated with a sugar facsimile of the royal coat of arms painted in red, blue, and silver. 

This slice is from one of the 27 cakes that were made for the Royal Wedding. It was baked by David Avery who was the head baker at the Royal Navy's cooking school in Kent and took him around 14 weeks to finish the cake. 
According to media reports, Chris Albury from the Dominic Winter Auctioneers said that the cake appears to be in the same condition. But adding a word of caution, he said it shouldn't be consumed for obvious reasons.
