Following last September's Farm Aid benefit concert, festival organizers had some of the legendary performers including Jack White and Willie Nelson autograph a Gibson guitar. Now you can have it for a mere $8,500 via the memorabilia site If Only.

The Les Paul 50's Tribute Vintage Sunburst guitar was also signed by Neil Young, John Mellencamp, Dave Matthews and Gary Clark Jr. The description for the guitar refers to it as "an incredible rock 'n' roll keepsake from one of the biggest music events of the year."

Since 1985, Farm Aid, with the help of its contributing artists, has raised over $45 million "to support programs that help farmers thrive, expand the reach of the Good Food Movement, take action to change the dominant system of industrial agriculture and promote food from family farms."
