This image shows a group of fierce looking german soldiers of an unknown regiment in Russia. Image was probably taken in 1914 or 1915. I first thought they were posing with a border sign or some military sign. As I can not speak or read russian I found a kind person on Twitter (@outskywalker), who translated it for me.
The sign reads: “General primary school in Voynov, 1st class.”
Quite funny, the double headed eagle and the cyrillic writing certainly looks seriously enough to fit the scene and to impress the families at home. I am quite sure they had no idea what the writing said.
