ALT A view of the spiral staircase at the British Library, with two visitors standing on the platform looking out at the space below.

ALT A set of 7 biscuits arranged in a square. In the top left is a biscuit version of the 1918 ‘inverted Jenny’ stamp. The royal icing has a scalloped edge, and the words ‘U.S. POSTAGE … 24 CENTS’ frame a navy-blue, upside-down image of a biplane. The top-right biscuit reads ‘The Lady’s Newspaper’ in ornate black lettering above a cameo of Queen Victoria. Below that is a biscuit depicting the title page of ‘The Tempest’ from Shakespeare’s First Folio. The bottom-right biscuit is inspired by a wax cylinder label: it reads ‘Genuine Edison Bell Gold Moulded Record’ in a vintage typeface. To the left is a large biscuit painted to look like a section of the Cotton Mappa Mundi, with patchy blue seas, red rivers, and turquoise mountain ranges. In the centre-left is a biscuit based on Lewis Carroll’s ‘Alice’s Adventures Under Ground’. ‘Chapter 1’ is written in a Gothic font above a hand-drawn illustration of Alice and her sister. The central biscuit features the British Library at 50 logo in gold.
