Royal wedding memorabilia was pouring off factory production lines Wednesday after Prince William and Kate Middleton confirmed they're to get married on April 29 next year.

The Prince William Pottery factory in Liverpool is set to manufacture hundreds of thousands of special mugs, each bearing the faces of William and Kate enclosed in a heart-shaped design. The mugs are expected to sell from around 16 US dollars in retail stores. Royal officials said on Tuesday that Britain's Prince William and his fiance, will marry in Westminster Abbey, the historic London church where Princess Diana's funeral was held.
