Not suren where to post this item, III Reich or Allied as they both have a link to it.
In fact it is not even military, and without its history and the village name mentioned on it, it wouldn't even be wurth looking at twice.
What is it? It's a warning sign from an electricity pole from Malmedy. It has the pre-war three digit phone number on it from the electricity firm, and it is a period piece. They were taken of the poles in the village, guess as a sort of souvenir of what had happened there, although I don't think souvenir is the right word. Don't think there are many out there any more.
Would it be of any value at all? Maybe to a collector of items of the Malmedy massacre, iff such collectors even exist?
Its just a very strange object, no clue what to do with it, or where it belongs. This one popped up last week.
