Editing Northern Pacific Railway (section)

==Trademark==
In search of a trademark, the Northern Pacific considered and rejected many designs. [[Edwin Harrison McHenry]], the Chief Engineer, was struck with a geometric design, a [[Taijitu]] in the [[Korean flag]] he saw while visiting the [[Korea]]n exhibit at the [[World's Columbian Exposition|Chicago World's Fair]] in 1893. The idea came to him that it was just the symbol for the long-sought-for trademark. With a slight modification, and rendered in red and black, the symbol became the railroad's trademark.<ref name="trademark">{{cite book |author = Wheeler, Olin D. |year = 1901 | title=The history of a trade-mark |url = https://archive.org/details/historyoftradema440whee |location=Saint Paul, Minnesota |publisher = Northern Pacific Railway}}</ref>

In 1876, photographer [[Frank Jay Haynes]] began contract work with the railroad for publicity photographs. In 1881 he met Charles Fee and through his 20-year friendship with Fee, Haynes became known as the "Official Photographer of the N.P.R.R". His "Northern Pacific Views" photographically documented over the years, the routes, destinations, infrastructure and equipment of the railroad.<ref>{{cite book |last=Nolan |first=Edward W. |title=Northern Pacific views: The railroad photography of F.
