Scientific American, Vol. 24, No. 20 (1871)
Scientific American volume 24, number 20, published in New York in 1871, is a weekly periodical for a general readership of inventors, mechanics and engineers. Its pictures are plain wood-engraved machine diagrams, showing treadle cranks on a sewing machine stand, a water wheel with buckets, and a crank wheel. A designer could draw on their clear, mechanical line work for technical or industrial-revival graphics.
