(10) SCIENTIFIC AMERICAN, New York, 1870's  A nice lot of ten issues from this fascinating period---the 'golden age' of American inventiveness---with much coverage of the latest inventions & improvements of the day, with illustrations. The images shown are only representative of the look, condition, and format of the issues you will receive.  Actual issues vary, but will be in equal or better condition than those shown, and will be dated in the 1870's.  Good shape.
