From Thinkgeek:

Throw away that generic mom with a shopping bag and dad with a golf club. Bring your automobile into the 24th century with this pack of Star Trek: The Next Generation Family Car Decals. It has all the main characters, plus some of our personal favorites from the series. There’s even a Borg Queen whom you can choose to display with or without her body. Don’t think too much about the implications when picking the stickers. The non-canon possibilities will hurt your head, and we don’t want that. What we do want is Young Jean-Luc Picard with a full head of hair! So cute!
