street sign with name of famous person
Street signs as such are not admissible, but does the situation change if the street is named after a famous or important person. E.g. in Germany, some streets are named after local or regional persons that were somehow important, and there is sometimes a small extra sign located below the street sign itself, the sign giving information about that person.
Hence, such a street sign is a bit more that a street sign as such, but is this sufficient to overcome the rejection criteria?
