You are looking at an item. This ball is signed by 29 members of the 1965 Giants. I am very confident this will pass any JSA or PSA/DNA authentication service. I got this in a massive storage collection find that was absolutely loaded with 1000s of items. Signatures are light but can read for sure Willie Mays Warren Spahn Bill Terry Juan Marichal l. Ball is an official Spaulding Warren Giles ball. I have no reason to believe that this ball is not authentic though there is a possibility that there may be a clubhouse signature here or there. I am selling it as is. I will include my 100% money back guarantee certificate of authenticity. Must for any collector. Shipping is free. Will be packed safe and secure in padded envelope with tracking.  Thanks to all our great customers all over the world....you keep buying and so do we....
