Tanner, the first native-born American to devote his career to map and atlas publishing, copyrighted this large wall map of the United States in1829. It depicts only the eastern two-thirds of the country, while the margins are lined with sixteen insets. Most of these insets document Americas major cities, including two pertaining to Boston.
At this time, there were only two states west of the Mississippi Louisiana and Missouri. The remainder of the Great Plains was allotted to various Native American groups. As evidence of the nations interest in manifest destiny, there is also an inset of the Pacific Northwest, recently explored by Lewis and Clark.
