The David Rumsey Collection dates this brochure to 1910, the year Glacier Park was created. But it is clearly from after that as the map shows all of Great Northern’s Glacier Park hotels, several of which were first opened in 1915. The map doesn’t show the Prince of Wales Hotel, which didn’t open until 1927.

Tour buses like the one on the cover were the first motor vehicles allowed in any national park. They were introduced in 1914 and the Glacier Park Transportation Company began to replace them in 1925. If this brochure were from after 1925, it would show a more recent model of tour bus.

The brochure also includes examples of Great Northern’s goat logo, which the railroad began applying to its freight cars in 1915 but didn’t begin using in advertising until after the Great War. The logo shown with the photos and on the map side was first used in 1922. All this suggests that the brochure dates from somewhere between 1922 and 1925, so to be conservative I’m going to say “about 1925.”

There’s no signature on either the cover art or the map. The map does say it was printed by McGill-Warner of St. Paul, which made maps for the Great Northern for many years.
