In case anyone's interested, just a little background on the "killed in action" ad. World Peaceways was an anti-war pacifist organization between WWI and WWII. Here's the text from the ad:
That ad (from my own eyes) could easily be used today. The issue is eternal and won't go away for a long time. Replace the graphic and modernize the font... Pretty much done at that point.
However, what you posted for the ad and the text there seem to be a bit different. There's a reference in the graphic to "1914-1918", but not in what you had. Perhaps there were different versions of it?
In any event, that one I certainly wouldn't paint as "crazy". Perhaps a vivid reflection of the time, but certainly not a crazy ad by any means. Crazy would be advocating war... Oooops! We have ads like that today!
