I had two posters for Buddhist Fist And Tiger Claws [1981] that match the poster image already there, but both were much clearer. I've uploaded the one which has a bit of light reflecting on it, because it's not too noticeable and the poster is much larger than the other, making the Hanja and Hangul much easier to read.
