Most O.T. Frasch images in the range from 270 to 279 show scenes from the 1909 World's Fair held in Seattle, the Alaska Yukon Pacific Exposition. There are also images of Lake Cushman on the Olympic Peninsula, 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.
A.Y.P.E. image 275 is notable because it shows Mary and Elsie Frasch posed at the exposition. Otto's wife and daughters lived in Lilliwaup, on Hood Canal near Lake Cushman, while he worked in Seattle. Perhaps he took them to the exposition one day and had them pose in a number of pictures.
