LONDON — Photos of Prince Charles and his bride-to-be Camilla Parker Bowles grace a set of royal wedding commemorative postage stamps unveiled by Britain's Royal Mail on Wednesday.

Britons will have a choice of two Charles and Camilla commemorative stamps, which will go on sale at post offices on April 8, the couple's wedding day.

A 30-pence (70 cents Cdn) stamp features a profile of the couple looking relaxed and laughing heartily, while a 68-pence ($1.6) stamp, commonly used for posting letters overseas, shows Charles and Camilla in a formal pose.

The photographs, which have been approved for use on the stamps by the Queen, were taken in Scotland at the Queen's Balmoral estate and at a highland games meeting in the country's north.

The Royal Mail's head of special stamps, Julietta Edgar, said the postal authority had issued commemorative stamps marking royal occasions for several decades.

"These stamps have long been recognized as one of the most prestigious, popular and enduring ways of marking such moments in our lives, and I'm sure these delightfully informal images will have the same worldwide appeal," Edgar said.

Prince Charles' first wedding, to Diana in 1981, was commemorated with a special set of stamps. More recently, royal stamps were issued to mark Prince William's 21st birthday in 2003.
