Wonder how many survive? "Images of German soldiers wearing their spiked helmets in the trenches are some of the most recognisable of the First World War. The famous 'pickelhaube' helmets were ditched in favour or ordinary steel ones in 1916, due to the fact that they were impractical for use in trench warfare. But it is less well-known that tens of thousands of the infamous head pieces later ended up being displayed on enormous pyramids in New York after Germany's defeat in the war. The US erected the structures on Park Avenue - which was temporarily renamed Victory Way - outside Grand Central Station in 1919 as part of a display of captured German equipment. Along with rifles, bayonets, swords, pistols and even artillery pieces, they were offered for sale and also given as rewards to those who had purchased war bonds. A new Youtube video by historian Mark Felton delves into the history of the helmet pyramids." www.dailymail.co.uk/news/article-10934805/How-12-000-German-spiked-helmets-displayed-New-York-WWI.html
