Not Boston. Boston has always been a city of the arts. It also was not the industrial hub as Baltimore was.

I lived in Philly in 1979, and see many of Baltimore's aspects in that town, though Philly is larger, was more prosperous. nor was part of the Jim Crow south. The neighboring townships were more developed and were not just farm settlements.

Richmond is a good contender, though it had less industry, but very much contained the Jim Crow aspects.
