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

 Art by (and SIGNED and numbered 193/212 in pencil by) Chuck Sperry, medium-thick stock silkscreen poster is in near mint (A-) condition; aside from a couple of TINY pinch dings in the lower margin/border and a VERY soft bend above the "B" of "Black", it is a KILLER example of this now 10-year-old Chuck Sperry poster from the OLF.

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