This is one of the exhibit halls at the 1909 World's Fair held in Seattle, the Alaska Yukon Pacific Exposition.
Note the spelling of "colonnade."
There is also an Image 201 (201 - From L.C. Smith Bldg. 42 Stories High) showing the L.C. Smith Tower, completed in 1914. Perhaps Otto reused the image number because no one would be interested in an A.Y.P.E. card after the exposition ended.
