The King's new royal cypher has been unveiled as the official period of mourning the Queen has come to an end.
The monogram, which the monarch personally selected from designs produced by the Royal College of Arms, will appear on post boxes, government buildings, state documents and other places throughout his reign.
His Majesty's design features his first initial C intertwined with the letter R for Rex – Latin for King – with III within the R denoting Charles III, with the crown above the letters.
