Otto took two photos of this high school from slightly different angles. It is difficult to tell which was taken first; neither shows much shrubbery around the building.
Note how "Seattle" is spelled in the second image; Otto was writing captions backwards on the glass negatives and sometimes misspelled words. The white spot above the word "High" appears to be the shadow of an insect; perhaps it landed on the paper prior to exposure.
