The four finalists in the county’s annual vehicle decal design contest have been revealed.

For the first time, the 2013-2014 decal contest included a theme. Entrants — the contest is open to Arlington high school students — were told to include a photo of the new USS Arlington in their design. They were also given the option of choosing a background color for the first time.

Arlington residents can vote for their favorite of the four designs via the Arlington County Treasurer website. Voting will close on Thursday, Jan. 24, 2013, and the winner will be announced at the Jan. 29 Arlington County Board meeting.

The winning design will appear on over 155,000 windshields.
