An uncommon 18th century miniature plan of Chester

A charming miniature, one of the few 18th century plans of Chester, with an eight-point key. It was published in Dury's rare pocket atlas, 'A Collection of Plans of the Principal Cities of Great Britain & Ireland, with Maps of the Coast of the Said Kingdoms, Drawn from the most Accurate Surveys, In Particular those taken by the late Mr. J. Rocque, Topographer to His Majesty'. This was designed as a companion to Dury's 'Universal Pocket Atlas'.
