Original 1st printing 23 x 17&1/2" (appx. -edges have been hand-trimmed) concert poster for Warren Haynes and Gov't Mule appearing at the Warfield Theatre in San Francisco, CA on 9/26/2009.

 Art by (and SIGNED and marked "B&W TEST" in pencil by) Chuck Sperry, this is an un-numbered BLACK-LINE-ONLY test proof/variant.

 Extra-thick index stock silkscreen poster is in fantastic near mint (A-) condition; aside from the aforementioned hand-trimming (which is somewhat negligible in this case) and a stray pinch ding or two, it is an overall SUPERB example of a VERY unique-looking Sperry test print.
