ambiguous perspective disguises ship's course in wwi

Above is a wonderful page spread from the February 1919 issue of International Marine Engineering. The article, titled "Principles Underlying Ship Camouflage: Complementary Colors Produce Low Visibility—Dazzle System of Ambiguous Perspective Disguises Ship's Course—Special Color Effects," was written and illustrated by Alon Bement, whom we've blogged about before. He taught art education at Columbia University, was a wartime camouflage advisor, and, interestingly, had a pivotal influence on his student, the painter Georgia O'Keeffe (as claimed by her). His ship camouflage diagrams are exceptionally helpful (there are more in the full article), as is the text. I think it would be fair to say that this is one of the best WWI-era articles on marine camouflage. I have reprinted the article, in its entirety (text and images), in my anthology of ship camouflage documents, titled SHIP SHAPE: A Dazzle Camouflage Sourcebook.
