I came across this image today when browsing through the newly released library of LIFE images that Google has scanned and put online. It’s an interesting image as it visually depicts the end of World War I as seen in wave forms of sound from one of the American’s sound ranging devices on the front lines. You can see it full size here.

The two splices of recording are from the few seconds preceding the cease fire by one minute and the seconds following the cease fire by one minute. It’s an amazing visual contrast and incredible to see a war end, almost as if someone had just switched off a light switch.
