This pictorial relies more on text than the ones of the last few days. It has three full-page photos and a fourth page with two photos. Three more pages have small photos but are mostly text and the last page is all text.
No date, but the trains are completely air-conditioned. Moreover, it states that Timberline Lodge was “dedicated June 13, 1937,” while Bonneville Dam “will be completed early in 1938.” So the brochure must be from late 1937 or early 1938. As we’ll see tomorrow, a similar Seattle brochure is dated January, 1938, so perhaps the Portland one was issued at the same time.
