Scientific American, Vol. 62, No. 15 (1890)
Scientific American volume 62 number 15 from 1890, a weekly American science and invention periodical published by Munn and Company in New York for inventors, engineers and general readers. Its pages mix patent notices, product woodcuts and advertisements. The pictures are small black-and-white engravings of inventions: a check punch machine with a printed cheque, a safety pin fixing a price tag to goods, and a pipe-mounted bracket holding flat-iron-like tools. A designer could take their crisp hatched line work and tidy labelled diagram layouts as a model for technical instructional graphics.
