I'm not sure that is actually true.   Where would they get a mask of William Shatner.

The back of “Starlog” magazine? That’s where I got mine.

"I'm not sure that is actually true. Where would they get a mask of William Shatner."

Read the article:

"The mask was originally made from a mold of Shatner's face for the Star Trek makeup department to apply appliances and alter his appearance. It was later found and used for the Halloween movie by the director."

Apparently, the mask disappeared after the cancellation of Star Trek and somehow ended up in a Halloween costume shop

It was a custom mask of his face that the make up crew used to create and practice “looks” for various episodes. After Star Trek was canceled it ended up in a costume shop and eventually became Michael Meyer’s mask.

Interesting trivia.
