Can anyone tell me if this Cassius Clay looks like a Vintage 60's autograph? On the surface, it appears it would be based on the date, but it doesn't really look like a 1964 version of his sig? Plus not sure if that type of market was around almost 50 years ago..
It is no doubt authentic, just trying to determine if it is indeed a early 60's sig, or possibly 80's-90's?? That way I can figure if it's worth the cost. I want it for a gift for my Dad :) Thanks!!
