Boris Karloff mask?

Watched a McMillan & Wife where Satanists are dancing around in masks that look like Boris Karloff to me.
I was wondering if this was a commercial mask available at the time?

It's weird seeing them without hair ... "weird" being a relative term, of course.

Keenan Wynn, Satanist: "I don't want us to look ridiculous so I got some Boris Karloff masks without hair to dance around in."

Forrest Ackerman had one of those DP Mad Doctor masks, done up as
Dr Scarabus from "The Raven". Can you see it there, just left of center?
