The Demonic Nun, Valak, in the movie The Conjuring 2. I think I know her.

Children in Peril in Alfred Hitchcock’s 1963 classic, The Birds.

I love this picture. It’s a group of people in formal attire wearing masks in, let us say, the 1930s. It could very easily have been at a country club or in a wealthy person’s home. Each person seems to be wearing a carefully selected mask appropriate for his or her age and personality. It must have been a fun party.
