I don't know later 'Williams' autographs, but this black-pen one should be obvious to anyone who has looked at even 2-3 authentic examples.
Of course, there are mitigating signing circumstances, such as alcohol or signing on a strange surface or at a strange angle. I had someone argue that a Mantle was good, but that he was just really drunk when he signed it. I guess if I were really drunk when I bought it, all would be well.
