One of the things that was so impressive about New York was the sheer size of the city, not only in terms of the number of people, but also the height of the buildings. We felt very small standing on the street next to them. The first picture shown here was taken while we were standing in line waiting to buy tickets to see West Side Story. I don't remember now what building this is, but its height is not at all exceptional for Manhattan.
The second picture is of a building which is exceptional by anyone's standards. It's the Empire State Building, now the tallest building in NYC. There is an observation deck on the 86th floor from which one can get a truly amazing view of the city. The picture was taken from the sidwalk across the street.
