“County Map of the State of Maine.” From Mitchell’s New General Atlas. Philadelphia: S. Augustus Mitchell, Jr., 1867. 13 1/2 x 10 3/4. Lithograph. Original hand color. Very good condition.
The most important Philadelphia cartographic firm of the later nineteenth century was founded by S. Augustus Mitchell, who was followed by his son, S. Augustus Mitchell, Jr. This map is typical of the output of the latter. It has Mitchell’s famous grapevine border and dense but clear detail. Also included is an inset of Portland in the lower right corner.
