designer's own words:The Car Replica is made of cut and folded heavy duty corrugated cardboard (including the base), printed waterproof plastic film and industrial cart wheels . The wheels work just like usual cart wheels: while the back wheels revolve, the front wheels keep going straight. All of them are hidden behind the fakes. Both, trunk and hood, can be flipped open by a simple strap hinge in order to store large amounts of material or access the box. While providing no less room for living needed, these Cardboard Replicas might even give a little taste of the american dream.
