Nice example of Tanner's map of the New England states, which first appeared in his American Atlas, which was issued in serial form between 1819 and 1823.
Tanner is one of the most important names in American Cartographic History. As a publisher, he produced seminal works such as Mills Atlas of South Carolina, many of the important large format wall and case maps by Melish, Austin and others and as an engraver. Perhaps his most important work is his American Atlas, which represented a breakthrough in quality, both in engraving and production, as well as the first elephant folio format atlas utilizing indigenous cartography to be published in the US. The atlas was published by Tanner and his son Thomas R. Tanner, for over 20 years.
