I worked on Market Street back in the mid to late 60's on the corner of 2nd and Market street fairly close to the Ferry Building. No top hats or horses but lots of bell bottoms,taxis and busses. Very noisy and sooty. This film must have been shot just before the big earthquake of 06 and sometime before the Hobart building I worked in was constructed. Neat !
I did get to ride out an earthquake on the 8th floor of the Hobart building while watching other wide eyed people in the windows of neighboring buildings sway back and forth. Not so fun.
