CONTEST IS NOW CLOSED - THANKS TO ALL WHO ENTERED

Winners will be announced shortly!

The celebration of U2's 25th anniversary kicks off this month with the release of U2 SHOW: The Art of Touring, a new book by Diana Scrimgeour, on October 21st. (U.S. release date)

The hardcover book chronicles U2's tours in words and pictures, from the earliest London club shows all the way through the Elevation Tour of 2001. U2 SHOW includes more than 500 photos, along with original interviews of Paul McGuinness, Willie Williams, Brian Eno, Daniel Lanois and many others.

And best of all ...

@U2 has five (5) copies of U2 SHOW to give away!

There's always a catch...

First, you have to answer a question correctly to be eligible to win. See below. Second, you have to live in the U.S. because we're only able to conduct this giveaway thanks to the generosity of Penguin Publishing U.S., and they can only ship to U.S. winners.

Here's how it'll work:

The contest will run from October 3rd through October 17th.

You must complete the entry form below in its entirety and get the simple question correct.

Five (5) winners will be chosen from all correct entries, and will be notified by email immediately after the contest ends. If you use super-aggressive spam filtering, be sure to allow the atu2.com domain -- the email you get will mention winning a prize, and some filters may think it's spam. We will give the names and addresses of each winner to Penguin U.S., and they will ship out the prizes. We will post the names of the five (5) winners on or about October 21st.

Answer this question:

The book cover image is posted below. Of the 12 images on the cover, how many are taken from the PopMart Tour? (Told you it would be easy!)
