Years ago, the Twig Case Co. founders each had a '66 VW Beetle, both of which required some tinkering. When we first picked up our copy of John Muir's "How to Keep Your Volkswagen Alive", Peter Aschwanden's amazingly detailed illustrations blew our minds. Here's our favorite, Exploded Beetle.
You can find more of his work on his official site: peteraschwanden.com. We're honored.
