Do you think $200 is a decent asking price?
I don’t know what this mask is or who it is by. Someone else will probably be able to tell you. I will say that I can’t think of a single scene in the movie where any of the masks looked anything like this. So for accuracy, I’d say no. That doesn’t mean it might not be a collectors piece though.
Its a NAG mask called the “Screen Used” which was based on the H4 Poster, its in the Gallery here.

I probably wouldn’t spend $200 on that as it’s not accurate to the H20 mask or H4 cover mask at all. Unless it’s got some crazy history behind it, I would save your money.
If it were me, I’d just completely rehair it and make it an H1 mask
This was meant to be an H1 mask. He called it Screen used and originally the hair was more tamed on them for an H1 look. This is literally NAGs attempt to actually sculpt something from scratch rather than a clay pour of something else. Granted, his work is better now than when he made these years ago, but they are quite crude.
