I wonder if anyone can help. I recently bought an Ali signed photograph and now have the collecting bug. I am looking to buy some new pieces and after looking on line I have seen a few things I am interested in. I was hoping for some advice on what is the best signature to collect (I'm going to buy a glove and some shorts). Is it 'Muhammad Ali aka casius clay' or 'Cassius clay' - these two options seem less common than the Muhammad Ali autograph. Unfortunately I can't afford a vintage one but they do come with online authentics. Any advice would be much appreciated.
