Ship In A Bottle 3

How many times are we expected to pay for Yinka Shonibare's old-fashioned Nelson's Ship in a Bottle, a 1:29 scale replica of HMS Victory, commissioned by London Mayor Bouncy Boris for the Fourth Plinth in Trafalgar Square? Presumably Bouncy paid for it then. Now the National Maritime Museum in Greenwich wants it. The Art Fund has put up £50,000 toward the £362,500 studio asking price and is appealing to punters to donate to its cause (title link). Forget it. Has Boris lost his receipt?
