“How Allied Pilots Recognize Japanese Warships from the Air”, a graphic that appeared in The Illustrated London News on 16 May 1942, displayed in silhouette the different sorts of Japanese warships that might be targets of allied planes.  There’s a lot of data on this one long sheet of paper, showing minelayers, submarines, aircraft carriers, battleships, cruisers, destroyers, subchasers, torpedo boats, training vessels and coastal defense ships–65 in all.  It is a great display, presenting a great amount of data in limited space, clearly and concisely, and very easy to distinguish and read.
