There are always things changing in New York City. Old buildings give way to new construction. We really have very little old architecture. Unlike Europe with buildings hundreds of years old, America is young and barely anything in New York is much more than one hundred. Every once in a while demolition occurs and just before they rebuild there is an old wall revealed. You get to see some very old advertisements for a brief period until the new construction covers it for a hundred years. Look while you can. It won’t come around again for a very long time.
