Masks from the middle highlands of Nepal, usually crude in design and dark with age, have always appealed to educated collectors. Though the masks look rough (almost ugly), they have an artistic power that can’t be denied. This picture, which I found on the internet, is typical. The only unusual thing is the metal foil stuck to the mask’s forehead. Think about the mix of Hinduism and Buddhism, and how these very poor people must make their own masks.
