It's hard to believe that the first four albums by one of the British Invasion's best bands have never been released on CD before. But they're finally here, gathered on 'The Animals: The Mickie Most Years and More' box set.

The five discs collect the group's first four LPs -- 'The Animals,' 'The Animals on Tour,' 'Animal Tracks' and 'Animalization' -- plus a bunch of extras. There are 61 songs in all. The set, released by ABKCO Records through Real Gone Music, also includes an Animals T-shirt.

You can buy the set here. But we're giving away a copy of 'The Animals: The Mickie Most Years and More' signed by singer Eric Burdon and original guitarist Hilton Valentine. For your chance to win the box set, follow the instructions on the widget above. Sharing your entry across Facebook and Twitter platforms will give you more opportunities to win. The contest ends on Dec. 30, 2013, at 11:59PM EST. Be sure to read the official contest rules, and good luck!
