Art Source International is proud to offer this reproduction map from the 1857 edition of Colton’s General Atlas. Colton atlases, especially those from the late 1850’s, have become increasingly rare. The General Atlas was the first single edition atlas published by the Colton brothers succeeding the expensive two volume Atlas of the World. The Colton firm refused to compromise quality, choosing to compete for sales in the finer quality international market rather than the cheap domestic one. Because of this, all maps were engraved by steel plates rather than by wax engraving which was the most common method used at this time. This city map of London is very detailed. It shows streets (named), railroads, parks, lakes and rivers, squares, government and public buildings, hospitals, and jails.
