This is the front and inside of the 2006 Christmas Card.
"Have you ever wondered how Santa finds out?"
In case you can't see it clearly on the website, the two stampers say "Naughty" and "Nice", the boxes are addressed "To: Santa", and the return address is the company logo. These all came through very clearly in the actual cards. The caricature is of the company owner doing a few background checks.
