The Jolly Roger Krewe is a private club/brotherhood in New Orleans.
The Krewe put on parades for Mardi Gras until its license was revoked in the 1990's. It then went underground and became more of a brotherhood than a club.
All members are required to wear a suit that makes them appear as skeletons.
Gilbert Buford is the Krewe's leader by the time of Bruno's death.
