Green Day Autographed Guitar - Signed By Billie Joe Armstrong, Mike Dirnt, and Tre Cool

Out of all the post-Nirvana alternative bands to break into the pop mainstream, Green Day were second only to Pearl Jam in terms of influence. At their core, Green Day were simply punk revivalists who recharged the energy of speedy, catchy three-chord punk-pop songs. Though their music wasn't particularly innovative, they brought the sound of late-'70s punk to a new, younger generation with Dookie, their 1994 major-label debut.
