I Don't Collect Autographs...
 

But I bought this M&M Olympics card of Cassius Clay because I liked the way Muhammad Ali added "AKA" to his autograph. I think it adds a bit of a personal element. At the very least it shows that Muhammad took time to look at the item he was signing.
You auto pros out there can tell me: is this a common touch by Ali when signing Cassius Clay items? At any rate, I really like it. I think I'll have it slabbed just to protect it.

Beautiful card

Thanks. I was hoping someone who knows about Ali autographs would chime in, but nothing so far.
