Win exclusive U2:3D posters

To celebrate the incredible U2:3D concert film (read review here) we have exclusive movie posters to give away.

U2:3D is a document of the band's Vertigo tour, and was primarily shot in Buenos Aires although other venues were used. Debuting on January 23rd, the film must be watched with 3D specs to get the most from it's groundbreaking filming.

We have 5 quad size (40 x 30 inches) cinema posters up for grabs (see the image above) if you can tell us:
