This is one of a very small number of O.T. Frasch images from outside the state of Washington. The photo was taken near Moscow (not "Mascow"), Idaho.
The image number appears to be "6-1". This style of numbering is used on some O.T. Frasch postcards.
We do not know the name of the man posed in the lower right corner.
There is also an Image 61 (61 - Union St. from 3rd Ave. Showing U.S.P.O. & White Bldg.) showing part of downtown Seattle. Reuse of image numbers and different image series make it difficult to know how many images Otto published.
