This mask slightly smaller than 1:1 was bought years ago in a job lot from Cydney Neil , (Rocky Point Horror House - Utah).
Lots of actors and fx guys worked there time to time and there are quite a lot of articles out there on Rocky point.
This mask is unfinished / uncut , but matches the carousel scene head bar the stitches, which may of been added cgi ?
Not sure if failed pull , proto type , production , extra made for Rocky point etc so selling as is ! Inc Rocky points paperwork.
