This is a complete set of nine maps and one panoramic view. The inside cover paste-down lists 6 maps and 1 panorama. The 3 additional maps are numbered 8, 9, 10 in the upper right corner, as are the first seven, which suggests the paper label is inaccurate and that all of the maps were intended to be issued in this fashion. The first six maps have brilliant lithographed color. The maps cover the region of Yellowstone, and parts of Wyoming, Idaho and Utah. All folding into original hardbound covers with gilt titling, missing most of the ribbon ties. Most sheets have some of the typical fold separations as described below. A scarce set rarely seen together.
