Calvin Klein Underwear and GQ have partnered up for an exclusive augmented reality advertising campaign across 12 countries, Twelve editions of GQ will run Calvin Klein Underwear’s new and first-ever Augmented Reality advertising beginning with the April issues which went on sale March 23rd. In support of its latest men’s introduction, Calvin Klein X Underwear. GQ.com will also run ads that will link directly to xmarkyourspot.com, a place where you can go drool over the some fine looking men looking all sweaty and greased and access all materials and videos featuring the campaign. If you don’t already know, the hunks wearing the undies are Kellan Lutz and Mehcad Brooks, Spanish tennis star Fernando Verdasco, and Japanese soccer star Hidetoshi Nakata. Just visit CK’s dedicated microsite at xmarkyourspot.com. Once in the Augmented ‘X’ section of the site, you can either hold up the ad from the magazine or a print-out of the AR code in front of your webcam. A 3D box will then appear which allows visitors to select from four short films created exclusively for GQ. Basically you’ll be holding Kellan Lutz in the palm of your hand….
