They’re “flat daddies” — cardboard cutouts of soldiers deployed overseas. The Bangor Daily News explains:

For the past year, Amanda Kelly and Erin Donnell have been bringing their Flat Daddies everywhere.Kelly’s Flat Daddy — a cardboard cutout of a loved one deployed overseas — is her husband, Sgt. Ryan Kelly of Lewiston; Donnell’s is her boyfriend, Sgt. Dana Gross of Levant. Both men are deployed with Maine’s 133rd Engineer Battalion at Bagram Airfield in Afghanistan.

Kelly and Donnell, who are friends, brought their Flat Daddies to the Brad Paisley concert on the Bangor Waterfront on Sunday night. They had no idea that Paisley, who has a long history of supporting the troops and military families, would reach and out touch them in such a personal way. During the concert, the country superstar grabbed Kelly’s and Gross’ cardboard likenesses, brought them up onstage and signed them.

The best news for Paisley, who was anxious to track down the identities of the two soldiers, was that the non-flat versions have been able to see him in concert as well.
