Mickey Mantle Team signed ball help?
 

So, I guess the first question is what do you think of this Mantle signature?

This is clearly not a great ball, as most of the sigs are fully faded beyond view. But there are a few (signed with the same pen) that are still readable, including Mantle's. But I can't read this one. Any help?

Mantle is not authentic IMO.

I have a 61 Yankees ball with an identical Mantle signature which was listed in the write-up about the ball as "clubhouse"

"Clubhouse" means not authentic. Ghost signed for Mantle by a clubhouse attendant. Very common in that era.
