Iron Staircase, Orient Mutual Ins, Wall St., NY, 1878, Original, Hand Colored

A Beautifully Detailed, Original Plan of the Iron Staircase in Orient Mutual Insurance Company, Wall Street, New York.  HAND-COLORED.  Alfred H Thorp, Architect(s).  From the American Architect and Building News, March 2, 1878.

This picture is extremely hard to find, as the American Architect and Building News not only had a very small circulation during that time, but very few were actually preserved or colored as this has been.  It measures 6 by 7 inches.  Has a mat border and foam core backing (not attached to the picture).  The whole plan measures approximately 10 by 11 inches (with mat border).  Finely detailed and beautifully hand-colored. Shrink wrapped.
