Creepy Smokey Bear commercial from the '70s

This creepy Smokey Bear PSA from the '70s features a seemingly normal lady who suddenly rips off her face, which is actually just a mask. She reveals that she is Smokey Bear in disguise.

If you pause the video at 0:21, you can see the terrifying mask coming off her face. I think this PSA would have been even more effective if it just showed the distorted mask the entire time, scaring people into practicing fire safety.
