This embroidered Hau Zua patch available exclusively here at The Black Broom, can be ironed on or sewn on. It measures 3 inches in diameter and has black stitching on grey felt. The emblem comes from a WWII German U-Boat - U256. "Hau Zua" is a phrase originally from the Austro-Bavarian dialect meaning "Hit them!". This phrase was commonly used to start a pub brawl.
