Last week we asked people to design some new wallpapers for GDA for a chance at winning [turl=http://www.greendayauthority.com/news/2470/]this autographed[/turl] 21st Century Breakdown special edition booklet.

We had an incredible amount of artwork sent our way, over 150 entries in all. It definitely wasn't easy picking the top 10. Actually I picked close to 50 that I through were really great, but we had to whittle it down to the top.

Check out the top 10 entries below, then vote for your favorite. All 10 are uploaded into the [turl=http://www.greendayauthority.com/downloads/wallpaper/]wallpaper section[/turl] for you guys to download. After the winner of the contest is announced, we'll be adding some more entries that we received into the section.

Thanks to everyone who took the time to participate. There was so much incredible artwork sent in.
