Ordnance Survey base sheets originally published in 1916 but updated by the LCC to 1940. Because they use the 1916 map, they give us a glimpse of a lost London, before post-war redevelopment schemes began to shape the modern city. The colouring applied to the maps records a scale of damage to London's built environment during the war the most detailed and complete survey of destruction caused by the aerial bombardment. A clear and fascinating introduction by expert Laurence Ward sets the maps in the full historical context of the events that gave rise to them, supported by archival photographs and tables of often grim statistics.
