Mickey Mantle Signed OAL Baseball Opinion

[canjond]

Unfortunately my father passed away unexpectedly and I am now in the process of trying to inventory his collection so I have a better sense of what he had and then make some decisions as to what to do with the items (most will probably be kept but some may become available for sale). He had a number of UDA signed Mantle items, but in addition to those, he had this Mantle signed ball (signed on a Bobby Brown baseball). It obviously isn’t the prettiest of Mantle signatures, but shakiness on the Ms aside, what does the board think of authenticity? I have no idea as to how it when it was acquired, although it’s not a recent purchase (my father hadn’t purchased items in years).

Thanks.
