In my searches for photos on the Library of Congress site, I found several in the Hudson River Port Folio of interest. From LOC:
Irish-born artist W.G. Hall spent the summer of 1820 traversing 212 miles of the Hudson River’s 315-mile course. 20 plates were engraved as aquatints by master printer John Hill and published between 1821 and 1825 by Henry Megarey in New York.
Vocabulary word for the day: acquaint:
a print resembling a watercolor, produced from a copper plate etched with nitric acid.
