A note on this map indicates it was engraved to be included in the 1858 edition of the D. T. Valentine Manual.

According to Hofstra University Museum website...

Valentine's Manuals, each volume officially titled, Manual of the Common Council of the City of New York, are a collector's valued treasure and a historian's basic reference. These books are a source of delight for the eye, containing as they do hundreds of maps, lithographs and woodcuts of New York City and times long past, often of sites long demolished. The Manuals are surely the first illustrated histories of New York City, the first comprehensive portrait of the City, and the first to use prints and maps relating to New York City so extensively and effectively. They are also among the first to organize and present a governmental record of the Corporation of the City of New York, including lists of offices, office holders, election results and financial summaries. In addition, they contain statistics as to numerous social and religious institutions, banks, hospitals, schools and any number of other related materials.
