The ball is in excellent condition and will be a valuable addition to your collection. Beautiful piece that my uncle had signed in person back in the 80's at the cow palace in San Francisco CA.It's absolutely authentic and I remember hearing all the stories behind this item and others that I'm going to list. You can easily verify the signature these days but I do guarantee the item to be what I say. The signature is in excellent condition and was signed over 30 years ago so he was much younger and you don't have a messey signature. Before you go check out my other listings.
