i don't believe i have ever seen this particular image taken from the angels flight observation tower looking east.
The photo is undated, but i'm gonna guess maybe 1911, due to the hulburt building standing, but the Ferguson building not yet. (i think i read somewhere that the ferguson building was completed in 1912....)
