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.

Paddington, also known as London Paddington, is a central London railway terminus and London Underground station complex, located on Praed Street in the Paddington area. The site has been the London terminus of the Great Western Railway and its successors since 1838. Much of the main-line station dates from 1854 and was designed by Isambard Kingdom Brunel. It was first served by London Underground trains in 1863, as the original western terminus of the Metropolitan Railway, the world's first underground railway. Today, Paddington tube station is served by the Bakerloo, Circle, District, and Hammersmith & City lines.

'So many irons in the fire and none of them hot,' Brunel wrote in his diary.

A common idiomatic phrase 'Too many irons in the fire' means juggling too many projects at once and something's bound to fail.
