The map is from 'A Concise History of Birmingham containing an Account of its Ancient State and Latest Improvements: together with a statement of the arrivals and departure of mails, stagecoaches and wagons, etc., etc.,' published by R Jabet and Co. , around 1817 it is a 5th edition and so was probably published and updated regularly; perhaps annually or bi-annually. There is no information indicating the date of the map but it reads, 'Drawn by Js Sherriff of Oldswinford late of the Crescent, Birmingham. The project to build the Crescent, modelled on the one at Bath, began around 1788. Thus the map was drawn somewhere between 1790 and 1815. The Crescent can be seen on the map towoards the top in the centre. It was by Cambridge Street behind Baskerville House. The last house standing in the Cresecent was the old Crescent Theatre.
