My wife was an honorary bat girl for a game at Busch in the 90s and received this ball. It appears to be the full team and more. Looks like Lou Brock is on there but he wasn't an active player at the time. Not sure what to do with the ball. It was left out and some of the signatures are faded. I'll post more pics for identification help in the comments.
Edit: Rod Brewer and not Lou Brock unfortunately. Still a good amount of hall of famers on the ball though.

Bernard Gilkey, Lee Smith, Jack Buck, Donovan Osborne, Todd Ziel, Bob Tweksbery, Ozzie Smith, Rex Hudler…just to name a few
My childhood just called.
First image: Bernard Gilkey, Lou Brock, Lee Smith, Jack Buck, Erik Pappas
Pappas and Smith make this 1993.
I was wrong. It's a Rod Brewer signature, not Lou Brock.
Does look kinda like Lou’s from what I recall though.
Bernard Gilkey, Brian Jordan, Lee Smith, Bob Tewksbury, Jack Buck, Ozzie Smith, Todd Ziel wow. That’s what I can ID, but that’s cool
I think the top name here is Bernard Gilkey, radio guy Jack Buck is second from bottom. I think the bottom name is Erik Pappas.
I think the second name is Rod Brewer.
Radio guy…..Jesus. The guy was only the voice of the Birds for nearly 50 years…
One could argue that “radio guy” is the most prominent sports figure on this ball not named Ozzie Smith.

The bottom one here looks like Todd Zeile.
Middle name here is Tracy Woodson.
Luis Alicia, Tracy Woodson, Todd Zeile

This is a repost of the original photo but wanted to capture the comments here.
Bernard Gilkey, Lou Brock, Lee Smith, Jack Buck, Erik Pappas
Edit: I think it's Rod Brewer and not Lou Brock. Pretty bad mix-up.

Gregg Jeffries is under Ozzie
Ozzie Smith, Gregg Jefferies, Bob Tewksbury, Joe Magrane
Top is Ozzie, third looks like Bob Tewksbury.
Top is Ozzie Smith.
Top name here is Ozzie Smith. That alone is awesome, assuming this is legit.

I definitely see Ozzie Smith, Jack Buck, Bernard Gilkey, Todd Zeile, Brian Jordan, and (I think) Bob Tewksbury on there.
In the first photo the first signature looks like Bernard Gilkey. The fourth one is Jack Buck.

This is a hat that someone signed.
You can figure out the rest from here. Definitely Brian Jordan in the last two.
