I fetched this autograph personally at the Hobbit Con 2013.
Not, that I am a fan of the movie, but simply because of the presence of Sylvester McCoy I had to go. I am a Whovian and the Seventh Doctor was reason enough for me to spent quite a lot time and money to meet him personally and get his autograph. In the end I got two autographs, the second on the picture from the photoshoot (he was actually quite excited about my t-shirt, and seeing it he shouted „Hey, I know that guy - that's me!".)
