I believe this is a preprinted signature. Not hand signed.
yeah probably, but couldnt find other examples of that photo on the internet with the same exact signature
If it is live ink, it is likely to be authentic.
it looks more like printed :(
but still cant find other examples of that photo on the internet with the same exact signature
It's a preprint. You can find it in Pete's article on SW actor preprints:
Scroll about a quarter of the page down. It's after a George Lucas preprint and it's in a photo that also contains a Peter Mayhew and Mark Hamill preprint.
