Autographed 1965-69 Chicago White Sox baseball

I do not remenber the exact year, but it was some time in the mid to late 1960's, my uncle took me to see the Chicago White Sox play at the old Comiskey Park. He knew somebody in management and managed to get me this autographed baseball. It has 27 signatures. I am not a big sports fan, but I do recognize the name Bob Locker, he played for the Sox from 1965-69.
Comiskey Park was closed in 1990 and demolished in 1991.
