Here's an alternate source that's much better and has better (but not enough) images: https://ny.curbed.com/2018/1/10/16868494/harlem-history-buck...
I don't really understand why this is the case, but a large percentage of stories about architecture, urban design, urban planning, development, etc. are written with thousands of words and no maps, diagrams, or pictures. The fuzzy black and white scribble on this one doesn't count.
Why do writers bother penning these? Architecture and it's assorted offshoots are visual media, and spending a bunch of words to describe it is about as useful as writing an essay to say what the Mona Lisa looks like.
