A set of 10 stamps celebrating the UK's most prominent cathedrals - including Lichfield - will be released today.
The stamps feature black and white photos of the interiors of six cathedrals.
A miniature sheet of four marks the 300th anniversary of the completion of St Paul's.
The four stamps combine an image of designer Sir Christopher Wren, the epitaph on his tomb written by his son and a photo of the interior of the cathedral.
The six other cathedrals chosen are Lichfield, Belfast, Gloucester, Westminster, St David's in Pembrokeshire and St Magnus Cathedral in the Orkney Islands.
The Royal Mail returned to a religious theme for its 2007 Christmas stamp collection following criticism from the Church of England the previous year about a lack of Christian images on the designs.
A Church of England spokesman said: "Royal Mail seek designs that depict life in the UK, and we are pleased that cathedrals are recognised as part of that."
Westminster Cathedral administrator Christopher Tuckwell said: "It is a tremendous honour for Westminster Cathedral to be featured as part of the Royal Mail's Cathedrals stamp series.
"Westminster Cathedral is the principal Roman Catholic Cathedral of England and Wales, and a sign of the Church's presence at the centre of our national life.
"The 72p stamp shows the magnificent nave of Westminster Cathedral, the widest of any cathedral in England, with a commanding view of the High Altar.
"I hope that this stamp makes more people aware of the splendour of one of the finest examples of Victorian architecture and Byzantine art in the world."
