Did Ali ever sighn an autograph Cassius Clay after 2/25/1964?

Question

I was under the impression that Ali would never call himself or let anyone else call him Cassius Clay after the first Liston fight and he adopted the Musslum religion.

Yet I am seeing a few things popping up on e-bay dated way after even items from the 90's with a Cassius Clay autograph on them, and selling for hundreds of dollars.

Could these be for real?

Answer 1

I would do my research before making any purchases...I know their were a great deal of fake items on the marketplace.  Ali appeared to be very proud of new found faith and not willing to have anyone disrespected his name or faith.
