Various publishers issued paperback booklets like this for selected rail routes, such as the Rio Grande (“Rocky Mountain Views”), SP’s Portland-San Francisco line (“Shasta Route”), and Union Pacific’s Overland Route (“Pathway to the Setting Sun”). While not railroad issue, they were obviously published with the cooperation of the railroads and were no doubt sold in train stations and possibly on board the trains themselves.
This particular booklet has hand-colored photos (at least one of which is based on a black-and-white photo by Asahel Curtis) along with a couple pages of text and a Milwaukee Road route map. The photos, nearly all of which show pictures of Milwaukee trains in scenic locations, are printed on white paper glued onto one side of a much cheaper grade of paper; so this 52-page booklet has just 23 photos including the one on the cover.
Someone has handwritten “J. Richard Haxton 1923, Returned to Pullman Wn from Detroit Michigan.” The $1.25 price of the book would be nearly $14 today.
On the inside back cover, someone else has pasted five business cards of J.E. Custer, an agent with Northern Pacific, whose time with the railroad apparently included stints in Walla Walla, Portland, and Seattle. Also pasted in is an early version of NP’s “Story of the Monad,” which I didn’t scan except for the two pages that happened to be open when I scanned the booklet that is part of the Spokane Public Library’s Northwest Collection.
