Scarce early map of Minnesota map, published in 1856.
This example includes wash color for the counties, unlike some of the 1856 issues.
This edition was published by Silas Chapman himself, who produced several pocket maps of Minnesota, Wisconsin, and Iowa. Chapman's maps were reproduced later by other publishers. While some 1856 versions of the map fail to show important geographic features shown here, such as Lake Minnetonka, the present map omits features that appear on other versions, such as the Sioux reservation in Goodhue and Wabasha counties and Houston county, indicating the present version is among the earlier states.
