Halloween Masks documents a group of animal masks Parkinson made for her children, nieces, and nephews from silk, papier-mâché, and acrylic paint. The masks grew from an informal tradition in which Parkinson created masks, puppets, and other sculptures for family and neighbors, extending theatrical invention into domestic and communal life; some of these objects can still be found in yards surrounding the family’s Berkeley Hills home. Much of her work was made for her children, for whom art became a shared language of play, transformation, and imagination.
