Fully titled Tallis’s Illustrated Plan of London and its Environs, this reproduction map measures 76x56cm. It was originally published in 1851 to mark that year’s Great Exhibition of Industry of all Nations, the location of which is marked in Hyde park on the map. Coverage extends from Fulham in the south west to Leyton Marsh in the north east. Hachuring (a style of hill-shading) emphasises the significant hills eg. in Greenwich Park and Hampstead Heath. Unobtrusively superimposed on the map is a 3 mile radius circle, centred approximately on Newgate Street near St Paul’s Cathedral. Around the margins of the sheet are small images of London landmarks.
