This illustration is of the VW Dormobile or campervan. The idea for it originated from the motorised trolleys that were used in the Volkswagon factory for transporting parts. They were made from stripped down VW Beetle chassis and became the basis from which a van was produced. It actually became the basis of everything from ambulances and milk floats to the much-loved campervan. The basic design remained roughly the same for four decades.
This example was commonly known as a ‘splittie’, from the split screen windscreen design. It’s rear-mounted, air-cooled engine initially produced 25bhp. There is also a POP Art print of the Volkswagon Dormobile Campervan available.
