This brochure is, by name at least, a successor to a 1931 28-page booklet that contained many color lithographs. The 1938 brochure unfolds into eight panels, so has about the same amount of space as a 16-page booklet. These brochures aimed to entice potential tourists to visit Union Pacific agents who would encourage them to take escorted tours or other trips to the Union Pacific West.
After the war, this brochure would be succeeded by brightly colored versions illustrated by the Willmarth studio. But before the war the railroad was content to offer this mostly sepia-toned edition, with a large map on the back that is both dreary and hard to read compared with its post-war Willmarth counterparts.
