Need help with one signature
 

This is primarily a 1966 Cubs signed ball except for Curt Flood - suspect he was a target of opportunity and this was signed at a Cubs Cardinals game. I thought the signature under him was Johnny Callison but it doesn't make sense since he was a Philly at the time. Any help would be appreciated.

An Old Timers Day ball?.....Are all the other sigs 1966 Cubs?

Got 14 other signatures all Cubs except for Flood and this one.

Does anyone think it is Johnny Callison? If so, I will consider it done.

I've had a couple of signed cards and it sure looks like Callison with a cramped last three or so letters.

Pretty sure it's Callison. The Johnny is spot on especially the way the H comes off the O and slants. Just looks rushed to me.

Thanks to both of you. I will put this one to bed with the mystery of a Cardinal and a Philly got on a Cubs ball remaining unsolved :>}
