Original 1st printing 20 x 34" concert poster for Ohio grease-rockers the Black Keys appearing at the Outside Lands Festival in San Francisco, CA on 8/13/2011. 

 Art by (and SIGNED and numbered 149/212 in pencil by) Chuck Sperry, medium-thick stock silkscreen poster is in near mint (A-) condition; aside from a VERY tiny pinch crease in the top center margin and a nearly-invisible handling ding or two hiding around the outer border area, it is a GORGEOUS example of this very colorful Chuck Sperry poster from the 2011 OLF.

 Check out audience-shot footage of the band's HUGE hit "Tighten Up" HERE:
