For the royal wedding of Kate Middleton and Prince William we produced a fine bone china mug. Except this one had a glaring mistake. Produced by a Chinese-sounding company Guandong Enterprises, the mug had Prince Harry instead of Prince William. Within a day of the launch the mug had hit media all over the world from the BBC in London to Ellen Degeneres in the US. And the mugs sold like hot cakes.
