The Photography collection at the Museum of the City of New York consists of more than 300,000 prints and negatives that document New York City and its inhabitants from the mid-19th century to the present. The Prints and Drawings collection encompasses architectural drawings, cartoons, portraits, mural studies, engravings, lithographs, maps, and fine art prints, and together with the Photography collection comprises one of the most comprehensive assemblies of urban iconography in the world. Its cornerstone is the extraordinary J. Clarence Davies Collection of images of New York City from the 17th through the 19th centuries, starting from the earliest known view of New Amsterdam, depicted in 1625-26. The Museum’s map collection traces the physical development of the city through early colonial maps of New Amsterdam, important Revolutionary era maps, 19th century real estate maps, and topical late 19th century and early 20th century maps illustrating such subjects as transportation, water supply, population, and the five boroughs of New York City.
