"Chehalis, Washington, and Mt. St. Helens. This friendly city, located between Seattle and Portland at the base of timbered hills, is the home of the Southwest Washington Fair."
If you click on and enlarge the image, you might be able to see Mount Saint Helens (when it still had a pointy top) on the horizon. Obviously this card was printed prior to the May 18, 1980 eruption.
Chehalis is known regionally as the county seat for Lewis County, for being a twin city of Centralia, and for hosting giant Yard Birds.
