In 1937, Canadian National changed its Rockies/Triangle Tour advertising from a booklet to a brochure. The brochure has the equivalent of about 18 pages of text and photos, which made it unwieldy to open and read, so this change seems questionable.

We’ve already seen a similar brochure from 1939. The two contain some of the same graphics and headlines, but the headlines are in a different typeface and the text is mostly different as well. Curiously, in 1940 CN returned to a booklet format for its Rockies advertising, publishing a 16-page booklet that had about 15 percent fewer square inches of space.

I found this brochure on archive.org, but its PDF is presented as if it was a booklet rather than a brochure. Using the 1939 edition as a guide, I pieced it together into a two-sided brochure that is about 21″x32″.
