Scientific American, Vol. 44, No. 12 (March 1881)
A single March 1881 issue of Scientific American, the weekly illustrated technical journal published by Munn & Co. in New York for inventors, patent-holders, machinists and general readers. The plates are wood engravings of machines standing alone in three-quarter view on bare ground or plank floors, with hatched shading, spoked flywheels, arched cast-iron legs and maker's names lettered into the frames, useful as isolated mechanical objects and as sources for cast-iron ornament and trade lettering.
