453-455 Broome Street, ca. 1975.

Built in 1872-1873 and designed by Griffith Thomas, this cast-iron building was the headquarters of the Hancock Silk Company. Hancock Silk was, for much of the 19th century, the oldest dress goods importer in the country. Founded in 1818 they went out of business unexpectedly in 1897.

In the 1920s the building housed A. Galewski & Sons, a leather and canvas manufacturer. During the later 20th century the building was converted into residential lofts and a ground floor commercial space.
