Coloured map of Middlesex and Hertfordshire from Jansson’s atlas of the world “Nieuwen Atlas”, Volume IV containing the English county maps, first published in 1646. The unusual western orientation of the counties creates a pleasing artistic composition. A description of Middlesex and Hertfordshire appears on the verso in Dutch. Other than a repair of a short bottom centrefold split and a few minor marginal defects, a strong dark impression on heavy paper in excellent condition. 43.5 cm x 54.5 cm
