I’d on a signed baseball
 

Tried this a few months ago with no success. Only answer was maybe 2 signatures. Any ideas. Joe

99% sure it is boxer Thomas Hearns.

It does look like his auto.

On a side note I trained with one of his amateur boxing coaches in the early 90s. His coach was also a high ranking black belt in Isshinryu karate.

Thomas "Hit Man" Hearns.

Thanks, I googled Tommy Hearns autograph. It does look close.
