These maps are highly detailed. They are taken from the OS 1:2,500 (or 25 inch) maps and reduced to about 15 inches to the mile. Each covers an area of a mile and a half by a mile. They show streets with individual houses, tram tracks, railway tracks and even signals, factories, wharves and such details as fountains and water troughs. They will provide hours of fascination for historians and genealogists. The maps are neatly folded and each includes a specially written introduction to the area.

This detailed map covers the ancient town of Malmesbury, described by Barrie Trinder as a "hill-top town of a kind more commonplace in Italy". It was a place of importance in King Alfred's time, a centre of trade in the 15th and 16th centuries, and the birthplace of Thomas Hobbes in 1588. However it declined in importance in the 19th century and had a population of just 2,407 by the time of this map. The publishers show it in detail, with features including the town centre, Horsefair, station, Cross Hayes, High Street, Abbey church, Holloway Bridge, Winyard Mill, silk mill, Mill Brewery, malthouses. Coverage extends south to Burton Hill and Burtonhill House. Eastward is a stretch of the GWR Malmesbury branch, and Cowbridge House. The map also includes a commercial directory of the town in 1907 and a timetable for the railway branch in 1929.
