In the socially and politically stratified polities of the Grassfields Kingdoms of Cameroon, the display and ownership of masks are important indicators of privilege and prestige. "Kwifoyn", a regulatory society whose members derive their authority from the Fon, or king, oversees all levels of criminal justice and functions as an executive branch of government. "Kwifoyn" is organized into ranked lodges; membership requires the payment of prescribed fees commensurate with each lodge's relative status. Among the privileges of membership is patronage of mask forms in celebrations performed in honor of its members. "Kwifoyn" also controls the right to license the replication of mask forms to lineage groups willing to pay a fee. Provenance: Monti Collection, Italia Joaquin Pecci, Bruxelles
