1965 Dodgers ball -- Clubhouse?

[earlywynnfan]

Purchased a random grouping of team-signed balls which included this 1965 (per Hector Valle being on it.) I know the sigs are light, but did the Dodgers still use clubhouse sigs in this era? I've included the Alston, Drysdale, and Koufax if you can make them out.

Thanks, Ken
