By now you know that Iron Maiden recently released a new live CD/DVD titled En Vivo! Filmed during their performance at the Estadio Nacional in Santiago, Chile on April 10, 2011, En Vivo! is yet another example of how amazing Iron Maiden truly is onstage. That’s why we’re excited to be giving away an En Vivo! bundle package that even fans who already bought the DVD will want to get their hands on.

More specifically, we’re giving away a prize package that includes a picture disc vinyl set, Steelbox DVD, Blu Ray DVD, and CD of Iron Maiden’s En Vivo! How can you enter for the chance to win this awesome package? Well, we here at Metal Insider HQ were recently debating what the “best” Iron Maiden cover artwork was. Maiden have had so many iconic covers that it was hard for us to agree on just one. So with that in mind, we want you to tell us which Iron Maiden album cover you think is truly the best in the comments section below.

We’ll be picking one winner by Wednesday, April 18. Multiple entries will be disqualified, and the contest is open to U.S. residents only (sorry, rest of world). So don’t waste any more time and enter for the chance to win this picture vinyl/DVD set of Iron Maiden’s En Vivo!
