Union Pacific Railroad, 1938.
Very good. Pictorial map, 18" x 31", folding to a 9" x 4" brochure (titled "Boulder Dam"), with text, illustrations, and colorful pictorial cover on the verso. A few pinholes at the intersections and tiny tears at margins, but overall a very nice example of this appealing map. which covers the region served by the Union Pacific Railroad from Salt Lake City in the north to Boulder City in the south, and from Las Vegas in the west to the Grand Canyon in the east. Various geographical features (mountain ranges, washes, canyons, and individual peaks) are identified, as are National Parks and Monuments.
