I have to say I agree with Rosberg and Button. I have never bought any photos or other items signed by drivers. First, I cannot be sure that they’re real. Second, it’s uninteresting and unemotional.
It is sometimes possible to get autographs even if you don’t go to races and don’t buy them. I have three autographs and I’ve obtained them in different ways.
The first one is from Heikki Kovalainen. I won it in the 2009 predictions championship organised by his official fansite (unless I’m mistaken, I was tied on points with @Enigma ).
The second comes from Marlon Stockinger, the Filipino-Swiss GP3 driver, who recently celebrated his first victory in the series (at Monaco). I got it sent to me after simply applying for it on the GP2/GP3 website (the series offered such an opportunity some months ago).
The third and the most personal one is from Alex Yoong, the former Malaysian F1 driver. I had bought his biography and left some positive feedback on his blog. He replied to me by saying he would sign it if I sent it to him. I did so now I have an autograph and a personal message from Alex Yoong.
