If I'm being honest....the work is interesting because it captures times and eras...
But a random flip through some flickr pages suggests to me in my humblest opinion that the vast majority of this work should have been edited out.
When i shot BW film, just like digital there were the keepers and then there was the rest...this guy posted the whole roll. A bad pic from 1970 is still a bad pic even if the character it captured was the coolest hippie ever.
