new Thurman Munson auto pickup , opinions ?

I recently Picked this Thurman Munson white index card auto up because I couldnt see anything that would lead me to believe it was not authentic. In my opinion its the real deal. I wanted some other opinions , do you all think its authentic and would pass PSA and or Jsa/BGS ?

640K ought to be enough for anyone.

There's people here who know a lot more than I do about Munson sigs, they can probably tell you more, and as you know he's one of the guys who didn't sign his name the same every time.
Good luck!

Can I ask what you paid for that one ?
Good luck on the authentication.
