This unsigned image has the writing of O.T. Frasch. The '2' in particular matches that on many different Frasch images.
Otto's wife and daughters lived in Lilliwaup, on Hood Canal at the southeast corner of the Olympic Mountains in western Washington. Several Frasch images of the Olympic Mountains are known.
There is also an Image 235 (235 - Yukon Ave. A.Y.P.E.) from the 1909 Alaska Yukon Pacific Exposition. Perhaps Otto reused the image number because no one would be interested in an A.Y.P.E. card after the exposition ended.
