A new series of six commemorative stamps has been issued to celebrate the Queen's Diamond Jubilee.

The Royal Mail's Diamond Jubilee Miniature sheet is the first to reproduce official portraits of the Queen in a series. It includes a new first class diamond blue stamp, which is due to replace the gold stamp this year.

One of the stamps features an image of the Queen from 1952, the first time her image was reproduced on a stamp.

Other portraits on the sheet of first class stamps reproduce pictures of the Queen that appeared on coins in 1953 and 1968, as well as those that were used on £1 and £5 bank notes in 1960 and 1971.

"Royal Mail is proud of our enduring association with Her Majesty the Queen. It is the company's honour to play a part in what will be an historic celebration of the Queen's Jubilee," said Royal Mail chief executive Moya Greene.

"The Queen's image is one of the most recognisable in the world and we are delighted to bring these iconic images together to mark the 60th anniversary of the Queen's accession."
