Very detailed maps colored to indicate townships containing and those "probably containing" lignite coal. Both maps were compiled and drawn by M. Hendges, and both signed in the plate by the "Geologist in charge, Economic Geology of Fuels." A historical pair that illustrated the search for coal to satisfy the growing energy requirements of the US economy.
Both with faint fold toning and browning on verso. Both professionally backed with archival tissue.
