Relatively early photo-facsimile copy of Elizabeth Shurtleff's fine image of the Shoals Isles or Smith Isles, originally published in 1927 by the Walker Lith. Co of Boston.
The map is apparently quite rare. We note copies in the Osher Library and John Carter Brown. The Portsmouth Library seems to have a bluprint copy done circa 1930. A small puzzle has also been published using this map image.
