Strong signature in blue. While there are signs of use, this is not a major league bat and there is no evidence it was used in a game by Bowa. We guarantee all uncertified autographs to pass 3rd party authentication with CAS our authenticator of choice. If you want to get autographs certified you need to notify us before you pay. We submit them for you. If an autograph doesn't pass we refund both the purchase price AND the authentication fee.
