Scientific American, Vol. 59, No. 2 (1888)
Scientific American volume 59 number 2 from 1888 is a weekly American science and engineering periodical printed in New York for a general readership of inventors, mechanics and engineers. Its pages carry wood-engraved line drawings of patented devices with lettered figure keys, such as a can opener, a ship's log and a railway car coupling. A designer could draw on the crisp hatching, cutaway views and numbered callouts for technical diagram styling.
