A lost gem

If this image of New York City’s Pennsylvania Station seems straight out of a classic film noir, it's for good reason. The photo was taken in the 1950s, just a few years before the US city’s beloved Beaux-Arts-style masterpiece was dismantled and then demolished, so that the Madison Square Garden arena could be built on top of its warren of walkways and train lines.
