1. Lannister Investment Group. As those who watch the show know, the real slogan of the Lannister House is, "A Lannister always pays his debts," which would be quite refreshing for an investment company.

4. Baratheon Security. LOL, you can "trust" them like Blackwater.
5. Stark Outfitters. This one is perfect, bravo, Shutterstock.
Smart branding move by Shutterstock. They used all their own stock photography to create these images. See all the images here.
