unlike the Lennon in a previous post, there is not one redeeming feature that I see with this signature. nothing. At least with the Lennon, even though it was non-typical, there were several positive characteristics. this could have been signed by my dog.
If it is authentic I pity the kid who scuffed up Dad's treasure. I can't tell for sure but it looks like the scuff mark came after the ball was signed. Always pays to keep extra used baseballs around for Junior to play with.
