Scientific American, Vol. 30, No. 22 (1874)
Scientific American volume 30, number 22, from 1874, is a weekly American periodical of science, invention and industry, written for engineers, mechanics and inventors. Its pages pair dense small-type trade advertisements for pumps, wood-working machinery and tools with large line engravings of patent devices and machines. A designer might draw on the crisp black-and-white linework, the ornate Victorian display type of the advertisements, and the schematic diagrams of machinery.
