This is the reflective glass bead type sign, much less common than plain porcelain. It has some factory blemishes that probably kept it from being authorized to be hung. It sat in a back room of a German dealership for decades.
The blemishes make it rarer... Similar to a double stamped coin or coin with an error. Not everyone will like that aspect, or don't care... But it's definitely uncommon.
