When I was growing up in St. Louis, MO, on the fringe of the Italian neighborhood called The Hill (or sometimes by a more vulgar term) you could always tell which cars were owned by Catholics by the little plastic statues on the dashboard. They weren't always of Jesus. There could also be Mary, Joseph, St. Anthony, or several others. Sometimes one car would have 2 or 3 of theses statues.

You can order your very own plastic Jesus from Catholic Supply of St. Louis. Look for "PLASTIC STATUARY- non-colored" near the bottom of the page. The web site doesn't say whether they come with an adhesive patch for easy dashboard mounting, but I wouldn't be surprised.
