Grand Amphitheatre Exposition, National Republican Convent., 1880, Original Plan

A Beautifully Detailed, Original Plan of the cross section looking towards the stage of Grand Amphitheatre Exposition Building, Used for the National Republican Convention, Chicago, Illinois.  HAND-COLORED.  W W Boyington, Architect(s).  From the American Architect and Building News, June 5, 1880.

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 by 8 inches.  Has a mat border and foam core backing (not attached to the picture).  The whole plan measures approximately 16 by 12 inches (with mat border).  Finely detailed and beautifully hand-colored.  Shrink wrapped.

Plan is in VG+ condition with very light browning and some minor crinkling.
