Chart

One framed nautical chart entitled "Port Facilities at Detroit, Michigan." The chart is printed in brown ink on white paper with topographical details enhanced in colored inks. It covers the area of the Detroit River from Lake St. Clair to Lake Erie. The chart was prepared by the Board of Engineers for Rivers and Harbors (of the U.S Army Corps of Engineers) at an approximate scale of 1/8" = 200' and is dated June, 1961. It is held in a plain brown wood frame and has a protective glass covering.
