The Rocklahoma festival may be over for 2013, but the participating acts have left behind a sign of good will that will ring out long after the final note was played. A number of artists on the bill have signed guitars and merchandise that they've contributed to a new charity drive by Rocklahoma's organizers designed to benefit those affected by the recent tornados in Oklahoma.

Alice in Chains have contributed a special, limited edition print signed by all of the band members. Co-headliners Guns N' Roses added a limited edition, artist-designed acoustic guitar that was signed by all the current members of the band. And Halestorm offered up an autographed drumhead used by Arejay Hale at Rocklahoma, as well signed drumsticks.

Asking Alexandria, Big Wreck, Bullet for My Valentine, Cheap Trick, Dokken, Hollywood Undead, Papa Roach, Ratt, Skillet, and Steel Panther all offered signed guitars, while members of the overall Sunday lineup also signed a black guitar to be auctioned off. Other items on the block include signed Clutch drumheads and a Bush autographed mat.
