Second 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 means Elizabeth II, by the grace of God, Queen.

Depicts the Library of Parliament building, the country name and the facial value above, the dates below.

Designed by Thomas Fuller and Chilion Jones, and inspired by the British Museum Reading Room, the building is formed as a chapter house, separated from the main body of the Centre Block by a corridor; this arrangement, as well as many other details of the design, was reached with the input of the then parliamentary librarian, Alpheus Todd. The walls, supported by a ring of 16 flying buttresses, are load bearing, double-wythe masonry, consisting of a hydraulic lime rubble fill core between an interior layer of dressed stone and rustic Nepean sandstone on the exterior. Around the windows and along other edges is dressed stone trim, along with a multitude of stone carvings, including floral patterns and friezes, keeping with the Victorian High Gothic style of the rest of the parliamentary complex. The roof, set in three tiers topped by a cupola, used to be a timber frame structure covered with slate tiles, but has been rebuilt with steel framing and deck covered with copper. The initial overall combination of colours—grey Gloucester limestone and grey Nepean, red Potsdam and buff Ohio sandstones, as well as purple and green slate banding—conformed to the picturesque style known as structural polychromy.
