Holliday topic: safety of car drivers and passengers.
Here is a thin postcard promoting stamp collection and writing, a card which was, I think, cut out a junior magazine and stick on a more concrete card.
The topic of the 2003 stamp is the ADAC (on the Wikipedia in German). Founded in 1903, the Allgemeine Deutsche Automobil-Club is a very pertinent, thoughtful and open lobby: civil patrol, repair mobile services (both by what appear on the stamp), diffusion of intelligence on many domains (local road laws and international too, gas, environment, etc.).
A whole lot of activities that surprised the French I am: I rarely heard of such things when French pro-car lobbies are speaking against government in France.
