About tickets, I bought mine for the Paris show via the Internet, but did not print them online and asked instead for a mail expedition, thinking I would get a real ticket, something to keep. Obviously, it was more expensive (approx 5 euros). And what I got was an A4 horrible sheet full of legal information... I really hope some marchandizing is going to be sold at the show, cos I don't want this thing to be my only "material" souvenir.
