Rare map of Middlesex, Essex and Hertfordshire

A large and detailed map of the three counties, marking the roads, with an inset plan of St Albans and a prospect of Colchester. The map is reduced from a six-sheet map by John Warburton (1682-1759), Joseph Bland & Payler Smith, published in 1724, with the map surrounded with 736 armorials of local nobles whose subscriptions paid for the publication. As Overton and Bowles were not getting the subscriptions this pirate dispenses with the armorials but adds the plan and prospect.
