Stephen King's It, Pennywise IT make up bust

original production material

“A Pennywise (Tim Curry) Make-up Test Head used in Tommy Lee Wallace’s film adaptation of Stephen King’s classic horror novel, It. In the film seven outcast kids are terrorized by Pennywise (Tim Curry), a demon possessed clown, and must face him again 30 years later. The clown head features a style of prosthetics seen when the kids launch a physical assault on the clown in the sewer towards the middle of the series. The Clown Head consists of a ceramic bust with a red wig, make up, and foam latex prosthetics in the style of those worn by Pennywise during the aforementioned scene.
The wig is 1 of the 3 that where used in the film so there is a good chance that this wig is screen used.
