This is a fun wall paper which coincidentally (?) relates perfectly to a Swedish candy: since the 1950s a candy shaped like a car has been produced and it is today a classic. Recently they introduced a ‘limited edition’ shaped like caravans – and every year they produce christmas trees as a special x-mas treat (the idea being that you bring home the three on top of your car, I guess). And these two are the only other shapes than the classic car shape! More info here but only in Swedish I’m afraid: http://www.
