This forum thread at Wired New York has an amazing amount of (mostly) black and white photographs showcasing the growth of New York from 1885, the early days of film-based photography, all the way to the 1970’s. It’s a great way to absorb what many say is the greatest city mankind has ever seen — New York.

Absolutely incredible set of photographers. It’s amazing to see a twenty year transformation from horses to cars.
It must have been some culture shock.
Didn’t New York have any “skyscrapers” in the 19th century? Chicago apparently had at least two back then. New York’s Singer Building was apparently the world’s tallest in the first decade of the 20th. As such New York used to have the world’s tallest buildings but now the tallest seems to be in Dubai. I believe an even taller building is planned for the city.
Anyway, I am featured on the BBC website and anxious to bring my weblinks to everyone’s attention. Simply visit Google and search the web for Jeremy Keller, or Jeremy Keller BBC, to access the details.
