The color chart below is a fold-out chart with paint, interior, convertible top and seat colors offered in 1964/65. The bug is on the front, the Ghia is on the back. I believe these were available as hand-outs back in 1964 to perspective buyers - at the dealerships. To it's right is the Service Book #1, and Service Book #2 below.
Below is an Original Volkswagen invoice. I have no idea what year it might have been used in.
Next, is the original Volkswagen Owner's Manual for the 1964! To it's right is a Volkswagen maintenance service sticker for the windshield. Again, not sure what year it might be from.
