I looked for a photo yesterday, but couldn't find one.
There is a suburb of Nürnberg, Germany, by the name of Fürth. And, as was the custom at the time, the larger cities (like Nürnberg and Munich) would take the first initial of the city's name (N and M) in these examples in the creation of their license plates.
Smaller cities would resort to TWO initials. Ansbach, for example, had the initials "AN" followed by an assortment of numbers.
In one example of Fürth's finest, a license plate was seen with the inevitable:
"FÜ CK 69"
