B No. 4 Showing the Progressive Changes in Sandy Hook from 1799 to 1851.

Interesting chart showing the temporal changes of Sandy Hook Head from 1779 to 1851. The lighthouse is depicted as well. There is also an inset map of Sandy Hook from the Light House to the Ocean House at a scale of 1:40,000 showing Horse Shoe Cove and The Cove.

IMPORTANT NOTE:

All of our United States Coast Survey (USCS), United States Coast & Geodetic Survey (USC&GS), and similar maps and charts have been professionally unfolded and flattened using humidity baths, semi-permeable membrane, and drying blotter techniques. Most others you typically see on eBay have not been, and worse, are quickly and crudely unfolded for the low-quality photos you see. Unfolding these maps in that way is damaging and weakens them. Please be aware.
