On the city market in Zywiec, a town in the south of Poland associated with beer production, I looked at the beautifully renovated facade of the town hall. In the background of the poster with the number 750 you can see the coat of arms of the city, of which a part is a head of Aurochs. It is an extinct animal that belonged to domestic cattle. In Polish, one of the appellation for domestic cattle is word Zywiec.
