The two great publishers of the nineteenth century of large scale county maps were the Greenwood brothers and Andrew Bryant (fl.1822-35). The elephant in the room was the Ordnance Survey which with government backing eventually forced them both out of the business. Bryant followed Greenwood into the business and published his first county survey, of Hertfordshire in 1822. There were a total of twelve county surveys and one of the East Riding of Yorkshire, the last being that of Herefordshire in 1835. This survey of Northamptonshire was carried out in the years 1824-6 and published 1 June 1827. There was only one edition.

A highly regarded detailed map drawn to the scale of one and a half inches to the mile. The Key shows that the detail includes amongst others individual buildings, castles, nursery grounds and gardens, canals, turnpike and mail roads, lanes and bridle ways, and even fox covers. The roads are shown with the distance from London in miles. The lower right contains a very large quality vignette of Peterborough Cathedral. Provenance: private English collection.
