This image of the Post Office and White Building was also copied by an unknown publisher:
M.L. Zercher of Topeka, Kansas also printed a copy:
Otto's original signature is still visible in the lower right corner above the new caption, but the original caption and image number have been cropped off.
We do not know if either copy was authorized.
There is also an Image 61 (61 - A Canyon Near Mascow) showing a canyon in Idaho. Reuse of image numbers and different image series make it difficult to know how many images Otto published.
