Most O.T. Frasch images in the range from 250 to 259 show scenes from the 1909 World's Fair held in Seattle, the Alaska Yukon Pacific Exposition. There are also images of Seattle parks and a steamer, apparently taken after the exposition ended. Otto may have reused the image numbers because no one would be interested in A.Y.P.E. images after the exposition ended.
