Camouflaging Buildings During WWII

These photos have been circulating the web for some time now, but they are pretty neat. They are supposedly of the Lockheed plant in California, where they used to manufacture planes. In any case, during WWII the USA was afraid of Japan bombing military and industrial targets on the West Coast. So one measure they took was to camouflage entire buildings too look like other typed of buildings or like they were just part of the surrounding environment. Pretty cool stuff.
