The ballon au poing is a popular team sport in Picardy (France).
To be able to hit the ball, players surround their hand and their wrist with a strip of canvas or leather.
The teams are separated on the ground by a line ( la corde - the rope) which is mobile during the party.
The purpose of the game is to gain ground by moving the rope.
Each 15 August at the Parc de la Hotoie ( Amiens ), the city receives the final stages of Ballon au poing.
