This isn't my item. I was able to get Tiger in person once before and it's fairly close. I'm a little on the fence about this item. What do you guys think? Authentic?
Hmm.. I was wondering about the "shakiness" too, but took into consideration I've got a few autographs where this is seen due to it being on a cardboard backing that wasn't completely straight. Just a theory as regular cardboard can naturally make that wavy type look when being written on.
