He started collecting autographs in the 1960s and only collect World Leaders. He hold 3 autograph exhibitions of his collection, latest one in 2009 in the Official Building of Members of Parliament of Hungary.
FC Barcelona is one of the biggest football clubs in the whole world. The club sells souvenirs for thousands of Euro year after year and hits next sales records. It seems to me that original, received in-person autograph could be better and more valuable item than next scarf or t-shirt. This is why so much fans decide to go to FC Barcelona training ground Ciutat Esportiva Joan Gamper in Sant Joan Despi. I was there several times and I did not regret at all even if I did not collect lots of signed photos.
Sebastian Vettel: All the time Sebastian was surrounded by his fans when he was on his way from the Red Bull hospitality to the pit lane. He tried to write many autographs, but it was very difficult because of the hectic around and because of the bodyguards. When he was able to sign his signature was ugly.
