The royal cypher that will be used to identify Camilla as Queen Consort has been unveiled.
It is made of up of the Queen Consort's monogram alongside a representation of the Crown.
The initials "CR" incorporates Her Majesty's initial, "C" for Camilla, and "R" for Regina - Latin for Queen.
It will be used on her personal letterheads and cards, as well as on the cross she will lay at the Field of Remembrance at Westminster Abbey in London, next Thursday.
The cypher is the Queen Consort's personal property and was selected by her from a series of designs.
It was the creation of Professor Ewan Clayton, a calligrapher and member of the instructors and academic board of The Royal Drawing School, in collaboration with Timothy Noad, Herald Painter and Scrivener at the College of Arms.
Professor Clayton lived as a Benedictine monk at Worth Abbey in Sussex in the mid-1980s and was later hired as a consultant to work at Xerox's Palo Alto Research Laboratory, in California's Silicon Valley, which helped develop ethernet and the laser printer.
King Charles' cypher was revealed in September.
His was designed by the College of Arms and shows his initial - C - intertwined with the letter R for Rex, Latin for King.
III is pasted within the letter R, all in gold, to signify Charles III with the crown above the letters.
King Charles's cypher also has a Scottish version, which features the Scottish Crown.
His monogram will be used on government buildings, state documents and some post boxes.
It will also be used by the royal household for franking mail.
Royal cyphers are monogram or monogram-like devices, typically consisting of the initials of the name and title of a monarch or their consorts, sometimes interwoven with but often surmounted by a crown.
Queen Elizabeth's EIIR cypher is on post boxes across the UK that were put up during her reign.
