London - If you're British and you win a gold medal, you don't get money. You get a mailbox.Well, your hometown gets a mailbox - or, as they say here, a post box.Well, actually, a post box in your hometown that is already there - and is of the traditional red variety - gets a golden makeover courtesy of the British Royal Mail.On Sunday, crowds gathered in the centre of the northern city of Sheffield, the home of heptathlon gold medallist Jessica Ennis, to see the gold paint being applied to a post box outside city hall.Turning red paint to gold is no easy task. It requires one coat of primer followed by four coats of gold.The cherry on the cake? As a gold medallist, Ennis also gets a postage stamp with her face on it. She does share that space with the queen, though.
