I am an avid collector of computer game promo posters, the sort that shops have up to advertise games.  Years ago I bought a poster of the 2009 game 50 Cent Blood on the Sand, when I got it home I saw that it was signed.

The signature says "50 Cent" but I cant tell if it's a real signature or not,  and I don't think it's printed on. I didn't pay more than I would for any other gaming poster and the seller's listing didn't mention it was signed.

Researching this is hard as I have never seen another example of this poster up for sale, and the game itself has "posters"as an in game collectable.

Seller was UK based, any information on this would be appreciated.
