Four new stamps are being issued by the Royal Mail in memory of the Duke of Edinburgh.
The black and white images show Philip, who died last month at the age of 99, at different stages of his life.
The first, a portrait of the duke as a young man, was taken by the photographer Baron, while the second is of Philip attending the passing out parade of his son, the Duke of York at Dartmouth Naval College in Devon.
Another stamp is of Philip at the Royal Windsor Horse Show, while the last and most recent image is a portrait taken by photographer Terry O'Neill.

"For more than seven decades he was at the centre of our national life. His passing is a key moment in our history which we mark with this set of commemorative stamps."
The four stamps are presented in a miniature sheet at a cost of £6.65. They will be on sale from June 24.
