The Crown Princess Couple's monogram was designed by the National Archives' heraldic artist, Vladimir A. Sagerlund. Crown Princess Victoria retains her letter monogram with the Crown of Sweden's Heir Apparent at the top.
Special permission is required for use of the monogram. The monogram should only be used for special occasions in consultation with the Royal Court.
Royal personages have used monograms since the time of the Vasa kings. The Bernadotte dynasty has continued to follow this tradition. A monogram was created for the newly-appointed successor to the throne, Karl Johan (Jean Baptiste Bernadotte), in 1810, featuring the initials CJ under the Crown Princes Crown. Following his succession to the throne in 1818, the open Crown Prince Crown was replaced with the closed Royal Crown.
Sweden's most proficient graphic artists were tasked with designing new royal monograms throughout the 20th century. Gustav VI Adolf's monogram was designed by Acke Kumlien.
Karl-Erik Forsberg created a monogram for King Carl Gustaf in 1973, and for the Royal Couple, King Carl Gustaf and Queen Silvia, in 1976.
The letter monogram CGS was used for the Royal Couple's wedding in 1976 on the parade cover that covered the steps from Logården to the East Gate for The King and Queen's entry into the Royal Palace. The wedding took place in Stockholm Cathedral. The King and Queen's face-to-face monogram was used on the invitations, among other things.
