Abstract: A universal costume mask armature is disclosed in which a rigid, preferably lattice, infrastructure including skull-shaped cranium and face portion is utilized. The face portion is preferably generally flattened and includes a pair of eye ports. A nose plate between the eye ports forms a continuation of the face and serves to receive and support nose features of a mask mounted on the armature. The face portion also includes a maxilary plate located below the nose plate to receive and support upper lip features of a mask. Use of this armature will enable a very wide range and variety of masks to be interchanged because the construction of the face portion of the armature is designed to support unlimited combinations of nose, eyebrows, beak, etc. without regard to their weight or size.
