I've only seen one authentic inscribed Sonny Liston in my life , Was part of a boxing collection I bought in London, that was signed in-person for the collector I bought it from. It was about a four line inscription written in BLOCK LETTERS ,
The collector who was known to Sonny and his handlers requested Sonny inscribe the photo to him. He was told to "Write Down" what he wanted Liston to write , he did and then was told to PRINT IT. Liston then just copied what he had printed and signed the photo.
Even the printing was a mess. I remember being told it was a very uncomfortable & embarrassing experience as The Bear hulked and labored over it for what seemed like forever.
