Joseph Colton began his publishing company in 1830 and became known around the world for the best grade of geographical publications. In 1860, perhaps struggling with financial difficulties, and with a new world atlas almost completed, Colton struck a somewhat mysterious deal with Alvin Jewitt Johnson, selling his engraved plates and General Atlas copyrights. Johnson & Browning immediately updated them with themselves named as publishers and "successors to J.H.Colton and Company" for the General Atlas.

Taken from Johnson's New Illustrated Family Atlas, With Descriptions, Geographical, Statistical, and Historical, this map is uncommon as it was published for a very short period. The strong decorative border used by Colton is still present in this version published by Johnson & Browning, an indication that this map was published almost immediately after the acquisition from Colton.

In 1862, Johnson & Browning introduced a "steel plate" version of this atlas and the decorative border changed. By 1865, the Colton name had been removed from all of Johnson's publications.

Bradford served as an assistant editor of the America Encyclopedia before entering the field of atlas publishing with his first work published in 1835. G.W. Boynton, the engraver of this map, operated an engraving shop in Boston between 1830 and 1845.

With the financial success of his 1835 A Comprehensive Atlas…, Bradford was able to update his maps, enlarge them and add a descriptive text to each. For map hungry Americans, these were attractive features to those interested in migrating during the burgeoning western expansion of the United States.

This map is from the 1st edition of An Illustrated Atlas….considered by most to be Bradford's best atlas, far superior to the smaller and more crudely drawn 1835 Comprehensive Atlas.
