Scientific American, Vol. 18, No. 9 (1868)
This is a volume of the Scientific American weekly from 1868, printed in New York for a general readership of inventors, engineers and tradesmen. Its pictures are plain black-and-white wood engravings of devices: a rat trap cut away to show its interior, a pair of bench-top measuring or drawing instruments in fine line, and small diagrams of an ice-making mould and press. A designer might take their clean, labelled line style and the way each object is shown in a three-quarter view with callout letters.
