The map on the cover of this booklet shows only a small portion of Colorado–basically, Colorado Springs to Fort Collins and the northern part of the Front Range of the Rocky Mountains. The Union Pacific served Denver and Greeley, but not Colorado Springs, and basically everything west of there was Rio Grande territory. This limited the booklet’s “Colorado mountain playgrounds” to Rocky Mountain National Park and a couple of adjacent national forests.
In addition to black-and-white photos of mountains and dude ranches, the booklet has exterior and interior photos of the M-10005 (or M-10006) City of Denver. Curiously, it doesn’t mention the Pony Express or other UP trains connecting Denver with the Midwest. It does have two pages listing Colorado hotels and resorts and their overnight and/or weekly room rates.
