Wall Street

Does New York have an "old city"?  About the closest we come is the southern tip of Manhattan.  Old maps outlining the location of the "wall" and the canals is all that remains of our early centuries. (Can I use that term when there is only four?)  This six marble piece is the result of a walk in that neighborhood two years ago.  Four of the images are from that area and two are from around 57th street.  Can you identify the sources?  Titled Wall Street it is now in a private collection, a print is available on the website.
