This is one of the first apartment buildings built in New York for middle-class tenants. It dates back to the 1880's. I believe it was equipped with a hydraulic elevator. (The Flatiron Building was running its ancient hydraulic elevator -- this means run by water pressure, folks -- until very recently.)
This is the photographer, that is, I. I'm wearing my Karl Marx disguise.
This image was made by digitally stitching the previous two images.
Second Avenue and 85th Street. Miraculously, the block has not been razed and replaced with faceless monoliths. I think four-story houses with roof cornices and window trim are very typical of New York, and very beautiful.
