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.

The cycling competitions at the 2012 Olympic Games in London took place at five venues between 28 July and 12 August. Cycling events have been contested in every Summer Olympics programme since the first modern Olympiad in 1896 alongside athletics, artistic gymnastics, fencing and swimming. Compared to the cycling at the 2008 Olympics, there were many changes in the Olympic track cycling programme. The men's and women's individual pursuit and points race, and the men's Madison were removed. Team sprint, team pursuit and keirin were added to the women's programme, while Omnium was a new race for both men and women. Countries were restricted to one entry per track event, a restriction which seemed to be directed at preventing the British team from double-medalling in the same event as they had in four events in 2008, thus lowering their medal chances. However, similar to the 2008 Beijing Games, the cycling events were dominated by the British team, which, with a haul including eight gold medals, was the only one to win more than a single gold medal.

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".
