A nice example of the first state of Thomas Jefferys edition of Lewis Evans' seminal map of the British Colonies in North America.
Along with the maps of Henry Popple and John Mitchell, Lewis Evans map is considered among the most important and influential American maps of the 18th Century and is the only one of the three to have been published by an American. Both Evans and Mitchell's maps were intended to spur western expansion into the Trans-Allegheny, Ohio Valley and regions westward and in response to French encroachments.
Evans' map became the standard for nearly 50 years, being re-issued Jefferys, Bowles, Kitchen and others. The map is a milestone both for its political significance and extension of cartographic knowledge in the region. Governor Pownall re-issued an updated edition of the map taken from the original Evans plate, with and addition of New England and a group of tables, naming townships in the Colonies. Pownall had been a great supporter of Evans and pledged the proceeds from the map to Evans' daughter. The cartographic importance of the map and its place in the history of cartography are substantial.
The present example was published by Sayer & Jefferys on June 15, 1775 and was offered separately for the published price of 2s:6d. The example here was apparently bound into a composite atlas and is in generally fine condition, with a fine dark impression and wide margins. Most examples of this map which appear on the market are from the American Military Pocket Atlas and have significant wear and fold damage, making this example, with only the single fold and wide margins an unusually fine example.
