1906 Game Used Baseball
 

I am new to this forum. But I have been collecting for many years. This is a ball I picked up years ago. It is written on by a fountain pen. It says “ Last Ball Used By Shumanns. Junior Champions 06. PENNANT” Hack Schumann was a pitcher for the Philadelphia Athletics in 1906. He pitched in the game on 10/03/1906 when the White Sox clinched the pennant. The ball definitely looks old but that is about all I know. Any thoughts?

It would be great to see a photo. Is it a Ban Johnson ball?
