249 West 17th Street, ca. 1910. Built in 1902, this six-story structure was the former warehouse for the Siegel-Cooper Dry Goods Store. The company got its start in Chicago in 1887 and expanded to New York City in 1896. At the time of its opening, the storefront was the largest store in the world. The building was designed in the Beaux-Arts style by DeLemos & Cordes, who later went on to design the R. H. Macy's store in Herald Square.
