Authenticity of 1962 team signed Cubs ball?

[nicker10]

Was interested in this auction and was curious if anybody had any opinion on its authenticity. Was a little concerned just because all the autographs looked almost as if they were signed yesterday but was not sure.

Any opinions would be greatly appreciated.
