It was difficult to read, but the note on top of the Queen's coffin in Westminster Abbey carried a heartfelt final message from a mourning son.
Handwritten by King Charles III, it read:
"In loving and devoted memory. Charles R."
The note lay on a wreath which contained flowers and foliage cut from the gardens of Buckingham Palace, Clarence House and Highgrove House.
They included rosemary for remembrance, and myrtle cut from a plant that was grown from a sprig of myrtle in the Queen's wedding bouquet in 1947.
Some viewers of the funeral noticed an additional visitor on the bouquet in the form of a small spider, which could be seen briefly in Westminster Abbey.
King and family joined coffin's London procession
Over a million people were expected in London for the state funeral, while 2,000 attended the service at Westminster Abbey.
The day began with a sombre King Charles and other members of the royal family walking behind the Queen's coffin as it was taken to the abbey from the nearby Westminster Hall.
The coffin was carried on the State Gun Carriage of the Royal Navy, drawn by 142 sailors.
Charles followed behind with his siblings Princess Anne, Prince Andrew and Prince Edward.
They were followed by the King's sons Prince William and Prince Harry and Peter Philips, Princess Anne's son.
During the service, the family stood near the front of the abbey, leading the mourners as they honoured the late Queen.
The service included emotional recollections of the Queen's coronation in the abbey as a young woman in 1953.
In the lead-up to the funeral, King Charles III told British media he was "deeply touched" by the support expressed for the grieving royal family from across the globe.
