Prince William and Catherine Middleton have officially sanctioned handmade plates, tankards and pill boxes as memorabilia, which feature the Royal Couple's entwined initials "C" and "W" in gold and silver, together with doves, white ribbons and hearts. They include a message, "To celebrate the marriage of Prince William and Catherine Middleton 29 April 2011". The profits from the sale of Royal Wedding Memorabilia will go towards the upkeep of the Royal Collection.
