Between 1881 and 1895 Louis Henry Sullivan and engineer Dankmar Adler designed a series of office towers, including the Chicago Stock Exchange. This historically important late 19th century ornamental cast iron interior staircase balustrade was salvaged from the building in 1972. The completely intact, straight section panel contains a nicely aged, uniform copper patina. Fabricated by the Winslow Bros., Chicago, between 1881 and 1895.
