Fake, fake, fake, fake... I don't care how many holograms or so-called letters of authenticity a seller provides, as far as I'm concerned, they're all fake.
The only signature I trust is one signed to me in person. Period.

I know of some signed posters with holograms that show they're legit, but they're UFC posters. The night of the fights, the UFC sells 125 official "signed by card" (everyone on the fight card) event posters and they have have holograms, numbering, and COAs. At the time I started this thread, I figured it was a similar dealio with the "world premiere" autos (forgeries), but in hindsight, and after doing a little research, the idea that studios would have a signing with some of the cast, for world premieres, is not realistic.
Of course, many cases of people getting ripped off, boil down to people not doing some research.
