There's nothing quite so satisfying as seeing a representation of quantitative data like this where the graphical displays are flying. "One Dreadnought Buys 52 Dirigibles and 235 Aeroplanes" is a full-page diagram appearing in the 3 June 1911 , making a very strong point that in the new air-age 2 million pounds for one battleship buys a lot of aircraft. Of course this is a British journal and the ship is flying an American flag--the image originally appeared in the Scientific American just a short while before this publication, and so it also enumerates American and international aircraft, making for a lovely representation of a broad range of airplanes filling up the same sky.
