I thought this was really interesting.
I love that kind of stuff... thanks for posting that.
Several things caught my eye:
People nonchalantly wandering out into traffic
People dressed much better than they do today. Some of those dudes looked pretty sharp, especially with those hats.
For 1911, the panoramic shot near the end showed that the city looked fairly modern. Having lived there for a couple of years, it didn't look all that different in many respects.
Must have been a pain in the ass to build those types of buildings back in the day.
good stuff NV
