This image appears to show the same park as Image 781 (781 - On the Shore of Lake Washington). The title may also be the same; part of what appears to be a letter 'N' is barely visible in the lower left corner of this image.
We don't know which park this image shows.
There is another Image 241 (241 - Arctic Brotherhood Club A.Y.P.E.). Perhaps Otto reused the image number because no one would be interested in an A.Y.P.E. card after the exposition ended.
