Scientific American, Vol. 27, No. 23 (December 1872)
A weekly issue of Scientific American from December 1872, published by Munn & Co. in New York for inventors, engineers, and patent-seeking manufacturers. Wood engravings show machinery in three-quarter view — flywheels, horizontal pumps, steam engines on masonry beds — plus workshop scenes of men at a press; useful for hatched metal surfaces, mechanical silhouettes, and inline label lettering.
