Speak Up has a great post about wartime propaganda posters — both real and parody.
Much of the conservation messages during the World Wars was brought about by actual need. Those wars devastated trade between western nations, and the need to conserve and to be as self-sufficient as possible was real. Times have changed, and it would take a truly global war to put the pinch on North America’s supply chains in a similar way. However, the parallels with the supply of fuel are obvious, and the lack of a major government-funded conservation movement, curious. Surely it is the most “patriotic†thing to do?
