Published by the Proprietors, Robson, Son & Holdsworth Leeds, John Hurst & C. Greenwood, Wakefield,, June 4th, 1817.. 1830 by 2170mm (72 by 85.5 inches).. Large engraved map in nine sheets, each sheet mounted on linen, fine original full wash hand colour. The maps by Christopher and John Greenwood set new standards for large-scale surveys. Although they were unsuccessful in their stated aim to map all the counties of England and Wales it is probably no coincidence that of the ones they missed, Buckinghamshire, Cambridgeshire, Herefordshire, Hertfordshire, Norfolk and Oxfordshire, all except Cambridgeshire were mapped by Andrew Bryant in a similar style and at the same period. From a technical point of view the Greenwoods' productions exceeded the high standards set in the previous century though without the decoration and charming title-pieces that typified large scale maps of that period. The Greenwoods started in 1817 with Lancashire and Yorkshire and by 1831 they had covered 34 counties. Their maps were masterpieces of surveying and engraving techniques, and in view of the speed at which they were completed, their accuracy is remarkable. They mark the boundaries of the counties, hundreds and parishes, churches and chapels, castles and quarries, farmhaouses and gentlemen's seats, heaths and common land, woods, parliamentary representatives and distances between towns. The price of 3 guineas each compares with the the first edition Ordnance Survey sheets of 7s 6d, though the latter did not relate to complete counties.
