“Map of Oregon, Washington, Idaho, and part of Montana.” Philadelphia: S. Augustus Mitchell, Jr., 1872. 10 3/4 x 13 3/8. Lithograph. Original hand color. Very good condition.
Mitchell’s map of the American Northwest from 1872, showing the increase in information available at the time. Of note in this version is a bold dashed line crossing Montana, Idaho and Oregon, and which branches with one line going to Wallula and another to Puget City. Though not identified, this is likely a proposed route for the Northern Pacific Railroad. Colorful and with a typical Mitchell decorative border.
