A LEGO 10220-like VW T1 "Bulli" camper.
I am not sure what year this would be, I just require it to be pre-60´ies...
This one even has a full interior. (See it on MOCPages or Brickshelf for more photos...)
Also credit to Richad Brown, whose original design this one is build upon! (With implementacion of ideas from Karwik and Misterzumbi too. Did I leave anybody out¿? ;-)
