A porcelain bowl belonging to Marie Antoinette is tipped to sell for as much as £1.8m after being discovered in a crate.
The "breast-shaped" ceramic was found in a container on a Paris estate after it had been missing for more than 200 years.
Its emergence has provoked excitement in the art world as it is one of a set of only four Sèvres porcelain bowls made for the French Queen in 1787 and 1788, with the others kept in museums.
