What a surprise! I was looking for a camera user manual in a messy cupboard, when I found a antique german postcard (First World War) I collected probably 20 years ago. It shows a horse from which has got a Prussian officer off, in order to help what I suppose to be a wounded soldier. The card is printed with the 4th verses of a Wilhelm Hauff's lied named Reiters Morgenlied (the Rider's Morning lied), also called Morgenrot, Morgenrot.
Obsessed by nose flutes and having a declining view, I immediately thought the officer was trying to heal the wounded soldier by applying a tin-plate Nasenflöte on his face.
Well... a magnifying scan shows I'm wrong, and the supposed nose flute was a metal glass of schnaps !
