Scarce St. Paul-published pocket map of Minnesota depicting the state from the Lake of the Wood to the Iowa border. The map extends eastward towards Wisconsin's Bayfield Peninsula.
Sewall was publishing maps out of St. Paul at the time of statehood. The present map was prepared at that time or a little thereafter - the county configuration dates it to circa late 1858. Contemporary evidence suggests that although the imprint date is 1857, this map was published in 1860.
