It has a bunch of really great pictures, like this one of the Ashgrove building right after it was built in 1910:

It also has pictures of the twin daughters who built the building, and their coal magnate dad:


These two sisters apparently built the Ashgrove building after their died killed himself by throwing himself in front of an IRT subway train.
Lots of weird scary happenings around this building. Kind of gives me the creeps when I walk by now . . .
Gonna keep looking for more info to post on this blog
