This glossy, 24-page booklet is undated, but it is clearly from the late 1960s. For one thing, a map on the inside back cover shows the St. Louis Gateway Arch, which was completed in 1965. The booklet also notes that, “Union Pacific Domeliners serve Denver from the railroad’s five main lines, bringing visitors from Los Angeles, San Francisco, and Seattle-Portland in the West, and Chicago and St. Louis in the East.” This statement only really made sense in 1967 or later, when all UP domeliners met and merged or split each day in Cheyenne.

This is one of those booklets in which the primary cover, shown above, is really the back cover. Even more peculiar, neither the front nor the back covers were printed with any reference to Union Pacific; the logos shown above are stickers that were very carefully applied to the same location on each panel.
