Gibson took its involvement with Live Earth to global proportions over the weekend, joining up Saturday with the 24-hour concert series to combat global warming in Hamburg, Germany.

There, some of Germany’s—and the world’s—most famous artists signed an exclusive Gibson Custom Acoustic guitar, which will later be auctioned off for charity. Among the celebrities to stop backstage to lend their signature were Amadito Valdez, Bianca Jagger, Chris Cornell, Cosma Shiva Hagen, Jasmin Wagner, Katie Melua, Lotto King Karl, Michael Mittermeier, Reamonn, Roger Cicero, Silbermond, and Snoop Dogg.
