Intriguing, and before reading your post I had never heard of such a thing - certainly an historical curiosity. But is it not to us astonishing that an otherwise upstanding adult alive in those times felt compelled to obtain and wear a mark which certified that he had repeatedly tried but failed to enter what almost certainly was/is the most awful wholesale waste of human lives ever brought about by arrogant leaders ? That the same carnage is to this day celebrated as something admirable/glorious is also rather grotesque.
