Mark's autograph

Hello fan club friends!
My name is Tomas and I am from Spain. More specifically of the Canary Islands. I am very happy to be a friend of this club. But in a way I'm also sad!, because I have never been able to go to any convention of friends of Star Wars Comicon. Since I suffer from a degenerative disease. I'm trying to get Mark's autograph. But I haven't achieved it for years and it makes me sad... I would like to know if you can help me achieve my dream of having a photo of Mark with his autograph. Please try to help me! Thank you
