Amazing metal board found in KL Gross-Rosen area, used in the electrified fence that surrounded the camp. It says in German: High voltage! Touching the line (wire) and also hanging anything is life-threatening. Panels like this one were hanging on the electrified barbed wire of lagers, so that nobody from the vicinity could dare to cross the line. KL Gross Rosen was also a gas-chamber-provided concentration camp. The overall condition of this panel is really good (still preserves the main part of the red, black and white colours), as it was preserved in the attic of a house that belonged to the camp complex and that now is a private house. It was recovered some days ago in Poland.
