This is the most ambitious Coloney & Fairchild strip or ribbon map: it shows the Mississippi River from its delta to its source at Lake Itaska, a distance of 2600 miles. It is backed on linen and rolls into paper covered spool with a hand crank. This is the revised edition, with much additional material added on river towns by William Bowen, President of the Pilot's Association of St. Louis (this information comes from the promotion for this map printed on the Ribbon Map of New York City). No record of the first issue found, although a copy exists at the Minnesota Historical Society. The river is colored blue against a black and white background. Distances from New Orleans are printed on the river at intervals to the source. Karrow's listing is for a variant: the map printed in five strips on one sheet and folded into the 1866 edition of Edward's Gazetteer of the Mississippi River. Scarce.
