Card models ??

Anyone ever done any paper/card models? I ask because I have noticed here in Poland a large and very active interest in card modelling. I suppose that during the communist era plastic kits were rubbish and card modelling was a good substitute. You can buy any type of ship tank aircraft etc. They also sell things like wooden road wheels for your paper tiger. They are very detailed and the scales various,how about a 1/100 Bismark or Titanic! The sailing ships are works of art and here as well you can buy brass cannons and wooden masts to replace the card for a stronger build. You can get 1/100 turned aluminium barrels for the Bismark!! There are many architectural subjects as well.
