Someone just informed me that the P-G film was fake and offered the Topstone Caveman mask as the linchpin to his conclusion. It seems this mask was a popular item in the 50's, with a movie appearance in 1958 in 'Frankenstein's Daughter." This was news to me, so I found the mask pictured on-line...what do you think?
