Scientific American, Vol. 42, No. 14 (1880)
Scientific American volume 42, number 14, published in New York in 1880 as a weekly periodical for a general readership of inventors, engineers and curious lay readers. The pictures here are line diagrams of ships, sails and shadows used to explain optics and the curvature of the earth, drawn with fine hatching and dashed sight lines. A designer could borrow their clean technical style, labelled ray diagrams and simple silhouetted vessels for infographics about light, horizon or perspective.
