Seattle's new city hall is visible at the far right. It is also shown in Image 18 - New City Hall Seattle and Image 173 - Yesler Way from Third Ave. Showing City Hall City Light Court House Dome.
The image is blurred in the lower left corner, perhaps due to a printing problem in the darkroom.
There is also an Image 19 (X19 - A.Y.P.E. Grounds from University) from the Alaska Yukon Pacific Exposition. Reuse of image numbers and different image series make it difficult to know how many images Otto published.
