There's something about a show which has a serial killer as its star that lends itself to creative visuals every season for Dexter.
This 'Avenging angel' billboard with Michael C. Hall sporting blood splatter wings is extremely arresting and perfectly captures the themes of the Showtime drama in its sixth season.
This eye-catching Dexter billboard was snapped along Sunset Boulevard at the top of La Cienega Boulevard on September 13, 2011.
Be sure to also check out these cool billboards for Dexter season three, season four and season five.
