Jack Charlton Autograph

[barstoolboy]

I am trying to verify if the autograph contained on the attached image belongs to Jack Charlton, and is indeed, genuine. Any assistance would be greatly appreciated.

[Five and In]

I've had several items signed by Jack over the years and it does have the "swirly" look of Jack's signature, but he usually signed in full as John Charlton.
As it appears to be on a programme, it may have been shoved under his face and he signed quickly.

Not a definitive answer, but I'd say 85% yes

[Sir Alf]

I agree with Five and In that he usually signed as John Charlton. I've got quite a few items he signed and to be honest this one looks a bit iffy to me, though I take the point that he might have scribbled it quickly. I'd not go as high as 85% personally
