Wills, Kate’s wedding souvenir mug features Prince Harry’s face

London,: A souvenir mug designed to celebrate the upcoming Royal marriage of Prince William to Kate Middleton could end up at the back of shelves for featuring Prince Harry instead of the groom-to-be.

The mug features photographs of Kate and Harry side by side, adorned with suitably royal flourishes and scrolls depicting their names.

On the back, an inscription reads: “The fairytale romantic union of all the centuries. 29th April 2011.”

The mug, supposedly designed by Chinese firm Guandong Enterprises, can be purchased for 9.99 pounds plus postage and packaging.

“Crafted in the finest bone china, it features an exquisite design of the happy couple with ornate gold detailing to honour this great moment in history,” the Telegraph quoted the website promoting the mug as reading.

“Please be our guests to own this esteemed, limited edition heirloom to celebrate with your work associates, friends, family and loved ones on 29th April 2011.

“You are welcome to purchase now to avoid disappointment and regret,” it added.

To avoid confusion, the small print states that the drinking vessels “are not supplied to, or approved by, Prince William of Wales, Catherine Middleton or any member of the Royal Family.”

A St James’s Palace spokesman admitted he was aware of the unusual piece of memorabilia but declined to comment.
