Enamelled metal board ground dug in the area of an unknown concentration camp that forbids touching the electric device. Condition is not the best since the enamel has some damage in some areas, but text is perfectly readable. It says "Das Berühren der electrischen Apparate und Leitungen ist lebensgefährlich und daher streng verboten" (Touching the electric device and the electrified fence is life threatening and because of that it's strictly forbidden). It was very common to find this kind of pannels hanged on the poles that holded the electrified fences of concentration camps, so that curious people that approached the area didn't touch it and try to enter the forbidden area. Very nice and rare, and really displayable for any collection based on concentration camp stuff.
