There are only two days left to cast a vote for which 2012-2013 decal you think should grace Arlington’s car windshields later this year.

Every year, high school students enter original artwork or photos into the Vehicle Decal Design Competition. A panel whittles down the entries to four finalists.

About 155,000 Arlington residents display the decals to prove payment of that vehicle’s personal property tax.

The four finalist designs, along with descriptions written by each student, are available online for viewing and voting. All votes must be submitted by noon on Sunday.
