This letterhead proclaims the Burlington Route as “The National Park Line.” The Burlington could reach Rocky Mountain and Yellowstone parks directly, and via its connections with the Great Northern and Northern Pacific it also reached Glacier and Mt. Rainier parks. Unlike the Union Pacific, which went to all of those parks other than Glacier, the Burlington didn’t get to Zion, Bryce, or the Grand Canyon. But its connections with the Rio Grande and Western Pacific brought it close to Mesa Verde and California parks.

I suspect this letterhead is from the 1920s, as the paper is finer than that used for the Aristocrat and other Burlington trains in the 1930s.
