Scientific American, Vol. 21, No. 8 (1869)
A weekly American science and engineering periodical from 1869, issued in New York for inventors, mechanics and general readers, carrying patent-office news and technical notices. Its pages show engraved mechanical devices with wood-engraved line drawings, some with lettered parts and captions. A designer might draw on the crisp hatching and dense machine detail of these cut-away engineering views for industrial or vintage technical graphics.
