This is a 6" by 8 1/4" photograph, not a postcard like most O.T. Frasch images. Every 'S' is backwards; Otto must have had trouble writing them backwards on the negative so that they would print properly. Other images have this problem, but not to this degree.
The black edges at the left and top are from the black mounting on which the photo is mounted. The photo is not quite square.
This image is almost identical to the postcard numbered 11 or "1-1" (1-1 - Administration Building A.Y.P. Eyxpo. Seattle 1909), except that the photo was taken from a slightly different vantage point and the flags above the building are limp.
Note the numbering: "no 29." The "no" appears on only a few images to date:
Usually the image number is alone.
There are two other images numbered 29:
Reuse of image numbers and different image series make it difficult to know how many images Otto published.
