Joker, The

Not the best work, just really old work. Kind of looks to me like you could cut the face down the center and have two good half pictures of the Joker but connected side-by-side, looks sort of skewed. Left side of the image... Where's the hook pulling the mouth back in dis-similar proportion the the right side? Or is it just me? He has a weird face, it may be just me. He is rather ill-proportioned at the best of times.
