One of the strangest wartime monuments of glory was the Victory Pyramid. There were two of these World War I showstoppers and they served a particular use. Words like "victory" and "liberty" were buzzwords for massive fundraising and advertising campaigns. War was a good way to get people interested. Well, the logic is sound, but the technique was sometimes lacking by today's standards.
In 1918, there were two victory pyramids in New York City on what was called "Victory Way," a stretch of patriotic and victory displays intended to draw the attention of passersby on Park Avenue. These pyramids on either end of "Victory Way" were quite large, towering over the street. The material they were made of was offered as a reward to big donators to the 5th War Loan. For every large donation, the donator got one of a total of 12,000 German helmets. That is right. The pyramids were made out of the helmets of the enemy.
The pyramids and other odd, passive-aggressive advertising tactics were used as part of a campaign to get people to buy war bonds. While the campaigns associated with "Victory Way" raised billions of dollars, it had little to do with the advertising tactics.
