This lot is a booklet comprised of eight maps issued at the end of fiscal year 1878 (June 30th). The maps are folding and contained in the original hardbound cover. Together, the maps cover parts of California, Nevada, Utah, Idaho, Colorado and New Mexico. Each map is numbered on verso to match the printed list pasted to inside cover, as issued. This original paper label lists the maps, with the fourth map lined out in contemporary ink, suggesting the map was not issued with this set.
