Marine engineering & shipping age
A 1921 trade periodical, Marine Engineering & Shipping Age, published in Philadelphia by Aldrich Publishing in conjunction with Simmons-Boardman, aimed at shipbuilders and marine engineers. The pictures are plain black-and-white photographs of cargo steamers in profile on open water, with captions naming vessels and their equipment, so a designer might draw on their clean hull silhouettes, rigging and deckhouse layouts.
