As a new Prime Minister is welcomed in, an old one is given a commemoration by being imprinted on a stamp.
Sir Winston Churchill is one of the images on a new series of Second World War stamps issued by Royal Mail, to mark the 70th anniversary of the Blitz.
The war time Prime Minister appears on one of the first class stamps in the Britain Alone collection.
Another of the 12 stamps features the less familiar faces of three young children being evacuated from London to Northampton.
The picture, taken in 1941, shows the evacuees with labels attached to their lapels, waiting at King's Cross station.
A 60p stamp in the collection depicts the three siblings - John Dawson, Barbara Southard and Rosemary Brett - reunited almost 70 years later to recreate the picture at the same station.
The trio relived their train journey to Chislehurst Caves and were filmed and photgraphed for the occasion.
Julietta Edgar, Royal Mail head of special stamps, said she hoped the stamp collection would serve as a "poignant reminder" of how much the country was affected by the Second World War.
She said: "After the fall of France in 1940, Britain suffered a period of huge uncertainty and grave danger brought into sharp focus by the destruction of the Blitz and the possibility of defeat in the Battle of the Atlantic."
The stamps, which will be on sale for a year, are issued on the 70th anniversary of Sir Winston's first speech to the House of Commons as Prime Minister.
On May 13 1940, he famously told the Commons: "I have nothing to offer but blood, toil, tears and sweat."
