This is another view of the Forestry Building, an exhibit hall at the 1909 World's Fair held in Seattle, the Alaska Yukon Pacific Exposition. The pillars are logs with the bark still on them.
There is also an Image 285 (285 - County Road Pierce's Summer Resort) showing a road on the Duckabush River north of Lilliwaup, where Otto's wife and daughters lived while he worked in Seattle. Perhaps Otto reused the image number because no one would be interested in an A.Y.P.E. card after the exposition ended.
