Legit sigs on 1958 Yankees team signed ball? Mickey Mantle Berra Ford
 

I have the opportunity to purchase this ball as part of a collection. Do the sigs on this ball look legitimate? I am focusing mainly on the Mantle and Berra sigs.
Sigs are on an NL Giles Spalding ball...not sure why NL, not AL ball...World Series time?
I just want to ask the experts before I consider this one.
Thanks in advance.

The Mantle looks wrong to me

Most of the sigs look pretty good, but i think the Mantle is definitely no good. It could be clubhouse. The Stengel is a little difficult to see fully, but I don't care for it either. The Berra looks OK.

The Mantle and Stengel are clubhouse. The rest are good.

Thanks Dennis, Mark and David. I appreciate your feedback.

I remember a post from a while ago where the poster asked for opinions on their Mantle signature. Someone replied that it looked more like the signature of Shakey Shantle and not Mickey Mantle. I still laugh when I recall that response. Appears that this one is close to a Shakey Shantle. :)
I will not be buying this ball.

Thanks again!
