Found this ball a couple years back but never got around to finding out if it’s real or fake. I’m a little iffy on that so I decided to just send it here
that is a 1967 Tigers team ball, with some cool signatures. In addition to Kaline it has what appears to be an authentic Norm Cash (many times his signature is clubhouse), the rare Mike Marshall, and Earl Wilson.
The signatures are legit. The Norm Cash is his signature, I have a single signed ball from him for comparison. As mentioned, the Mike Marshall is very rare, he hated signing.
