One of the Citroën-internet pioneers, Marcel Reimer, started an internetgame in 1997 by sending some of these cards by e-mail to a number of internet Citroën freaks. They could earn more cards when you answered difficult cryptic questions, the answers could be found on Citroën pages all over the internet. You could also change cards with other participants. The first one to have all 36 published somewhere on the internet received a free meal. That was on a nice and happy night in a restaurant with a number of other participants.
