The Firemen's Memorial facing Riverside Park on Riverside Drive at 100th Street, 1913. The NY City Parks Department website says[1]:

The memorial exemplifies a classical grandeur that characterized several civic monuments built in New York City from the 1890s to World War I, as part of an effort dubbed the City Beautiful Movement, which was meant to improve the standard of urban public design and achieve an uplifting union of art and architecture. This monument has twice undergone extensive restoration, once in the late 1930s, through a W.P.A.-sponsored conservation program, and more recently through a $2 million city-funded capital project completed in 1992.

History of New Deal Art Projects: “In 1933 and 1934, during the period of The Great Depression, the Federal government's Public Works of Art Project (PWAP) was organized by the Civil Works Administration. The general purpose of the program was to give work to artists by arranging to have competent representatives of the profession embellish public buildings. This program lasted less than one year, yet it provided employment for approximately 3,700 artists who created nearly 15,000 works of art. In 1935, a similar project, the Federal Art Project (FAP) was established by the Works Progress Administration (WPA). The Federal Art Project continued until 1943...”
