Going through my childhood collection, and I found this old ball with several signatures on it. It used to be my Grandfather's, and the ball I believe was given to him by the old MLB manager/scout Herman Franks probably sometime in the 1960s, who is among the signatures I am certain of (Franks was an old family friend on my Mom's side; I even got to meet him once at his house in the mid-late 1980s when I was a kid. He was super nice, signed a bunch of stuff for my brothers, cousins and I, plus gave us a bunch of unopened 1978 Topps cello packs!).

The signatures (I believe) I can identify are:

Herman Franks (only one I am certain of)
Ty Cline
Ted Abernathy
Leo Burke
Jim Proctor
Steve Hamilton

Can anybody help me identify any of the others (or correct those above)? (Unfortunately, the ball was not well cared for, so some of them are very faint).

Also, any ideas on how this collection of (seemingly random) players may have come to be on a single ball?

Apart from Ty Cline who played for SF in 1967-68, they don't seem to overlap with Franks' managerial career (SF 1965-68, Cubs 1977-79)...

Any help is greatly appreciated!

Thanks, David
