Scarce engraved mapsheet with a pair of images showing the city of Boston and Boston Harbor.
The map was engraved by John Lodge and published in the London Magazine in 1774, on the eve of the American Revolution. It was no doubt issued as increasing tensions in the colonies drew British attention there.
The map includes a key in the lower left, which references specifically the map of the city of Boston. It says:
IN 1735 this TOWN was divided into the following 12 Wards each of which keep a Company of Foot.
The key thus placing obvious emphasis on keeping public order.
The References section names Town Hall, Faneuil Hall, the Governors House, the Old North Meeting, the Old South Meeting, the Prison, among other noteworthy locales.
