As previously shown here, in the 1960s the Great Northern issued a series of what I call “tiny brochures”–because they fold to just 2-5/6″x5-1/2″–describing each of the many destinations reachable on GN rail. This one for Alaska appears to date to 1959.
Although similar in size when folded, they don’t all unfold the same. This one unfolds into a page that is almost exactly 8-1/2″x11″. The ten color photos in the brochure include, among other things, Anchorage, Ketchikan, a Baronof fishing village, Mt. McKinley, and the above cover photo of a glacier in what looks like Glacier Bay.
