First state of Henry Schenk Tanner's map of Asia and Australia from is American Atlas.
Tanner commenced production of his most ambitious project, his American Atlas, in 1818. Released in 5 folios between 1819 and 1823, the Atlas is widely regarded as the single most beautiful large scale American Atlas ever published. The maps are large, detailed and elegantly engraved. The production resulted in the split of Tanner from his partners Kearney & Vallance, but resulted in the greatest of American Atlases.
