Need help with sigs
 

Hello!

I am having a hell of a time figuring out who signed this, an help would be greatly appreciated. I'm from the bay area if that helps. It wouldn't surprise me if they were all either Giants or A's players.

Thank you!

Bill North upper right (with the #4).

First ball, top signature is Chad Harville.
First ball, bottom signature is Scott Hatteberg.

The bottom ball looks like Dave Kingman.
