Untapped Cities has photos from an exhibition of historic and antique maps of New York City at the gallery of Manhattan rare book dealer Martayan Lan. New Amsterdam to Metropolis: Historic Maps of New York City features maps of the city dating back to the 16th century. It opened last November and runs until the end of May 2019. Some (but not all) of the maps, the New York Times notes, are for sale, which is what happens when it’s a rare book dealer rather than a museum or library doing the exhibition.
