Ortsschild of Nürnberg

To speak truthfully, I don’t understand a postcard such as this.  I understand that some people actually collect this specific type of postcards.  This type of postcard depicts an “Ortsschild” which in German means “Placename”.
 
I would have preferred a touristy card of Nuremberg (Nürnberg).  It would have brought back some memories of this city that I visited in 2004.
 

 

Nuremberg (Nürnberg) is a city in the German state of Bavaria. Situated on the Pegnitz river and the Rhine–Main–Danube Canal, it is located about 170 kilometres north of Munich. It is the second-largest city in Bavaria (after Munich).
