Queen Elizabeth II or American actor Tom Hanks? A new porcelain bust of the British monarch based on a confectionary box really takes the biscuit for some art critics.

Celebrated Chinese sculptor Chen Dapeng made the 20-kilogram artwork - the biggest piece of Chinese porcelain ever made - which will be offered to the queen as a gift.

The bust, apparently based on an image of the Queen embossed on a tin of biscuits, took three months and 12 tries by a dozen technicians to fire before a lucky 13th attempt held together.
