Collection of views by Percy Loomis Sperr depicting the boroughs of Manhattan, Bronx, Brooklyn, and Queens, capturing New York City during the Great Depression until just after American entry into World War II. Sperr specialized in streetscapes, focusing on buildings and infrastructure, though passersby make occasional appearances in his compositions. Physical change in the city's appearance was of great interest to Sperr, and this collection features views of the dismantling of the Second Avenue and Fulton Street Elevated train tracks, and the construction of the Belt Parkway. The collection contains 335 photographs in four volumes, housed in 3-ring binder boxes with table of contents.
