Founded in 1923 to document the city's history, the museum holds the Stettheimer dollhouse, whose miniature gallery contains an original work by Marcel Duchamp.
It's smaller and generally far less crowded than the major Fifth Avenue art museums, making it a good stop for visitors who want NYC history without long lines.
