(It measures 5ft 10in (1.78m)high and 3ft 5in (1.05m) wide and 4in (11cm) thick. It takes six people to lift it. It was presented to Charles II on his restoration and is now 350 years old. It will be displayed for the first time as one of the stars of the British Library's big summer exhibition of maps.)
