Fourth crowned portrait of HM Queen Elizabeth II facing right, wearing the Girls of Great Britain and Ireland tiara.

The Girls of Great Britain and Ireland tiara was a wedding present in 1947 from her grandmother, Queen Mary, who received it as a gift from the Girls of Great Britain and Ireland in 1893 on the occasion of her marriage to the Duke of York, later George V. Made by E. Wolfe & Co., it was purchased from Garrard & Co. by a committee organised by Lady Eve Greville. In 1914, Mary adapted the tiara to take 13 diamonds in place of the large oriental pearls surmounting the tiara. At first, Elizabeth wore the tiara without its base and pearls but the base was reattached in 1969. The Girls of Great Britain and Ireland Tiara is one of Elizabeth's most recognisable pieces of jewellery due to its widespread use on British banknotes and coinage.

ELIZABETH II DEI GRATIA REGINA FIDEI DEFENSATRIX means Elizabeth II, by the grace of God, Queen and Defender of the Faith.

Wrestling at the 2012 Summer Olympics were held between 5 and 12 August, the final day of the Games, at ExCeL London. It was split into two disciplines, Freestyle and Greco-Roman which were further divided into different weight categories. Men competed in both disciplines whereas women only took part in the freestyle events, with 18 gold medals awarded. Wrestling has been contested at every modern Summer Olympic Games, except Paris 1900.

Wrestling is a combat sport involving grappling type techniques such as clinch fighting, throws and takedowns, joint locks, pins and other grappling holds. The modern history of wrestling begins with a rise of popularity in the 19th century, which led to the development of the modern sports of Greco-Roman wrestling on the European continent and of freestyle wrestling and collegiate wrestling in Great Britain and the United States, respectively. These sports enjoyed enormous popularity at the turning of the 20th century. In the 1920s, show wrestling as a form of sports entertainment, now known as professional wrestling, separated from competitive sport wrestling, now known as amateur wrestling.

The London 2012 Summer Olympics logo is four abstract shapes placed in a quadrant formation spelling out "2012". The word "London" is written in the shape representing the "2", while the Olympic rings are placed in the shape representing the "0".
