Picture of Young Joan Crawford kind of freakin' me out

I stumbled onto this last night, and now I can't quit looking at it. Young Joan Crawford looks like she really wants to stab someone.  I recommend you not look directly at the picture for too long.  Use one of those boxes you're supposed to make to look at the eclipse.  In this way, you are less likely to find yourself driven to madness.

As terrifying as I find Young Joan Crawford staring impassively into the camera, if she broke into a smile, I think I might pee myself a little.
