Grand Staircase of Francis I, Chateau de Blois, France, 1885, Original Plan

A Beautifully Detailed, Original Plan of the Grand Staircase of Francis I at Chateau de Blois, France.  HAND-COLORED.  Unknown, Architect.  From the American Architect and Building News, February 28, 1885. 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 12.75 by 17 inches.  Has a mat border and foam core backing (not attached to the picture).  The whole plan measures approximately 16 by 20 inches (with mat border).  Finely detailed and beautifully hand-colored.  Shrink wrapped. Plan is in VG+ condition with light browning along the edges and some light crinkling.
