We’ve seen this brochure before, only it was blue and advertised Union Pacific trains instead of Great Northern. The brochure was actually designed by the Alaska Steamship Company and co-distributed by Union Pacific, Great Northern, and possibly other railroads.

Other than the color, the backs of the two brochures are identical. The biggest difference about the fronts is a panel that Union Pacific used for photos of the Portland Rose and the Columbia River Gorge, which Great Northern used for the Empire Builder dining car interior and Glacier Park.
