An unusual circular panorama of wartime London

A complete 360º view of London as seen from the roof of the Bank of England in Threadneedle Street. It was drawn by Bank employee Arthur Bond between June and August 1944, when he was an A.R.P. (Air Raid Precautions) warden stationed on the roof to watch for the new V-1 cruise missiles aimed at London. It was originally intended to be a 'roof-spotter's guide', allowing correct identification of the buildings under threat, but eventually 200 examples were published to present to members of staff who had served as firewatchers. At the centre is an allegorical figure representing the Bank, surrounded by a circular map of London of a mile radius on a scale of 6", with the ring view between two grids of degrees. The view is printed in black, brown and blue to denote distance from the Bank: under ½ mile, between ½ mile and four miles, and over four miles. Underneath is an extensive key of buildings, also using the colour code. A rare item.
