Measuring Things in Terms of Aircraft Carriers–Tokyo, 1925

JF Ptak Science Books   Quick Post

Here’s an unexpected bit of data visualization:  at the tail end of an obscure pamphlet —A Sketchbook of the Activities of the Japan Wireless Telegraph Co., Ltd.–a 26-page work published in Tokyo in 1925 was this fine and unusual-looking chart of comparative heights of Japanese structures. This also includes two of my favorite comparative unit comparables–upended ships (#s 10 & 11), including the aircraft carrier Akagi (#11).
