Mask used in Halloween 2018 Jamie Lee Curtis promo pictures?

Hi everybody- sorry if this has already been discussed, but in the first promotional pictures released for Halloween (2018) that announced the return of Jamie Lee Curtis, she’s shown in her original outfit (sans long hair), along with Michael Myers standing behind her. Another closer photo shows the both of them laying on the grass, next to each other. Does anybody recognize the mask used in these pics? I doubt they’d custom make something just for promotional pictures, especially since it’s nothing like what was used in the film. I don’t know if it’s the lighting or how large and bulbous it seems, but it peaked my curiosity.
