Lake Cushman, northwest of Shelton in Mason County, Washington, was a favorite topic. Otto's wife Mary and their daughters lived in Lilliwaup, just a few miles away, while he worked in Seattle.
There is also an Image 281 (281 - Hoo-Hoo House A.Y.P.E.) showing the Lumbermen's Club at the 1909 World's Fair held in Seattle, the 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.
