Letterheads, cards and gifts from the British Queen Camilla will be monogrammed with an elaborate monogram.

This was announced by Buckingham Palace on Tuesday night.

The monogram consists of the two intertwined initials CR (Camilla Regina) and a crown that appears to float above.

Regina is the Latin word for queen.

Camilla's husband, King Charles III, also has a monogram, which is now featured on new mailboxes and government documents, for example.

It consists of a C for Charles, an R for "Rex" (Latin for "king"), the numeral III within the letter R, and the symbol of the crown.

The transition to monograms should be gradual if, for example, mailboxes are exchanged anyway.

In addition to mailboxes from the long reign of Queen Elizabeth II, there are also a number from the time of her predecessors in Great Britain, right up to Queen Victoria, who died in 1901.
