Besides the Weaver autograph, has also been signed by Lydell Mitchell, Tom Matte and Dave Joyner. There are an additional 3 signatures we were not able to identify. The cover was removed from the rest of the program and glued onto a piece of black construction paper, so wedon't have the guest list to use for clues. We guarantee any autograph we sell to pass 3rd party authentication with CAS, our authenticator of choice. If you want to take advantage of the guarantee you must notify us before we ship. Once you have taken possession of an item it is yours!
