You may need a folder full of views ... this one has 18, which fold out as you can see in the photo above. Title: Souvenir Folder of Scenes Along the Northern Pacific Railroad. The folder is ready to be addressed and apply postage for mailing, perhaps to a friend, to show them what you have just seen on your journey. Probably issued in the 1920s or 1930s. Published by J. L. Robbins Co., Spokane, Washington. Folder # 3326, and, in another spot 3326 - 6170. Most of the views are labeled so we will let them speak for themselves.
The Northern Pacific Railroad provided passenger service between Chicago and Seattle among other points. It was famous for its service to Yellowstone National Park's northern entrance, seen in the view above.
