This very early map of Iowa Territory was issued in the May 29, 1841 edition of the New-York Observer, a weekly religious journal. It depicts the territory with only twenty counties nestled along the Mississippi River and locates a number of towns and settlements, with Iowa City shown as the capital. The map was included to promote Morse's newly developed cerographic process. These "teasers" would later be issued as supplements from 1842-1845 (in three parts), as the Cerographic Atlas of the United States. The present map of Iowa would only be seen in the 1842 edition, as all later maps would also include Wisconsin.

The full newspaper measures 22.1 x 27.6".

The map is clean and bright with just a few small spots in blank areas. The overall newspaper is in remarkable condition for its age with some light staining mostly in the blank margins.
