Here is a detailed tour of buildings in New York. I tried my hardest not to placemark places which have already been placemarked so you will not find the following:

->Empire State Building
->Chrysler Building
->Flatiron Building
->Trump Building

Plus more. However, there are many other skyscrapers of that time in this guide. Each placemark contains statistics on the building such as construction dates, heights, floors, arcihtects plus any other bits of info.

I hope you enjoy.
