I did not get the ball in person, it was given to me by a family friend and it has 2 signatures I know (Kenny Rogers and Mark Buerhle) but these others I do not know. Instead of me just never knowing, I decided it would be smarter to ask a group of people who would have better knowledge than myself. I apologize if I am not fully learned on all the possible autographs on items that are in my collection, I will work on that.
The only one that I could even come close to identifying was the one that I said looked like Kirby Puckett. If it is in fact Kirby's signature it is very atypical. I was comparing it to images that I found on Google that looked slightly similar. Here is an example of what I am referring to. Keep in mind that I am not sure how authentic the example is since I found it on Google Images but the seller is claiming that it was authenticated by JSA. Other than that I am at a loss.
