The map is probably based upon a copy of the 'Ryther' map, now in the Bodleian Library, which has an extension - in pen and ink - westwards to Pall Mall and Lambeth House. The omission of the Stuart's royal coat-of-arms would suggest that the map was printed at some point in the 1650s. Howgego suggests a date of 1655, as the imprint upon the map is the same as present in Thomas Porter's 'New Book of Maps...' published in 1655. To the upper left is the long title, set within an elaborate title cartouche. In the title, the wish is expressed that the map "is a ready helpe or Guide to direct Countrey-men and Strangers to finde the nearest way from one place to another". To the right are the St George's Cross, the Harp of Ireland, and the Cross of St. Andrew. Further right, the City's arms are flanked by personifications of Justice and Prudence, and a list important "Streets, Places, Hills, Lanes, and Allies (sic) which for want of room could not be written". To the lower right is an elaborate compass rose and scale bar. The plan itself is finely engraved and shows Westminster and Lambeth House (Lambeth Palace) in the west to Lyme-House (sic) in the east, Pall Mall is written 'Pell Mell', and the grand houses and wharves along the Thames are named. Upon the Thames, ferrymen, barges and sailing vessels are shown.

Only two other examples of the map are known: the one in the British Library's Crace Collection (Crace 34), differs from the present copy by the naming of 'Bowe Street' in Westminster. Upon the present plan the street is named 'Theeving Lane', which was the street's earlier name; therefore the present copy predates the Crace copy. The other example, housed at the Society of Antiquaries, is an even later state, and bears the royal coat-of-arms. It was later reproduced in facsimile by the London Topographical Society in 1898.

Scale: approx. 6 inches to 1 statute mile.
