Scientific American, Vol. 44, No. 6 (1881)
Scientific American, volume 44, number 6 from 1881, a weekly American technical periodical for engineers, inventors and manufacturers. Its pages mix dense classified advertisements for machinery, patent novelties and industrial supplies with engraved machine drawings. The engraved plates show a lithographic or printing press and a three-view cabinet or fixture drawing, with clean hatched line work a designer could borrow for technical diagrams and vintage trade layouts.
