Marine engineering
Marine engineering is a 1920 periodical from New York publisher Simmons-Boardman, aimed at shipbuilders and marine engineers and covering the shipbuilding trade. Its pictures include technical charts of ship stability and freeboard curves, a photograph of a cargo steamer under way, and a catalogue-style illustration of an adjustable wrench, which suggest plain line graphs, engineering diagrams and utilitarian machine drawings a designer could borrow for dense data layouts.
