Alec Guinness didn't like Star Wars or is role in it.
He did it for the money, but I've heard from several interviews he thought Star Wars was silly.
So putting his Obi Wan photo on his page is not something he would have wanted.
I read his autobiography years and years ago, and while he was very polite about his experience in "Star Wars"... he did say that making the film made him realize that he could be doing something more meaningful with his Golden Years.
He did NOT say anything about working with the Worst Actor's Director ever. Most definitely not.
