These two covers are unrelated at first glance, but together they show a little of the narrative of the life of Queen Elizabeth II.
The first celebrates happy times. King George VI, who had been on the throne since his brother's abdication in 1936, celebrating the marriage of Princess Elizabeth to Prince Phillip, which took place on the 20th November 1947. At first I read the letters as "ER" for Elizabeth's royal monogramme, then I reminded myself that she was not yet Queen, and the initials are of course "EP", for Elizabeth and Phillip.

The second is a little sadder. Following her Father's death in 1952, Elizabeth was crowned Queen in 1953. The juxtaposition of the King's head still on the stamp, overlaid with with the words, "Long Live the Queen", is an poignant illustration of this moment of change in the monarchy.
