Attractive map of North America, hand colored by states and territories. Shows oversized Dakota, Indian Territory and an early Alaska (no longer Russian) Territory. Nice detail throughout the map. From one of the leading American map publisher of the 1870s. From the true first edition of Gray's National Atlas.
O. W. Gray was a publishing firm based in Philadelphia. Later, they published as O. W. Gray & Son. They published atlases in the late nineteenth century. Gray's National Atlas was one of the most successful commercial ventures of the 1870s and one of the last to employ hand coloring on maps.
