My first instinct is that it looks authentic. I haven't paid super-close attention to Braun, but he's out local star and Waukesha Sports cards and Legends of the Field have done several signings with him. That looks right to me.
I hope you're instinct is right, Rich. It came with a COA from a company that has something of a reputation for passing forgeries. And I have actually been to Waukesha Sports Cards in person, and it is absolutely great. Makes me wish I had more money every time.
