Original 1st printing 20 x 26" concert poster for Nirvana appearing with the Butthole Surfers and Tad at the Seattle Center Arena from 1/7-8/1994.

 Art by (and SIGNED and numbered 166/300 in pencil by) Lee Bolton, medium-thick oak tag stock hand-pulled silkscreen poster is in near mint to excellent (A-/B+ to B+) condition; aside from a couple of tiny thin pinch bends and little edge dings around the outer margins, a few light surface scuffs and a slight curl to the paper, it is in pretty nice shape overall.

 Here's the entire 1/8 Nirvana set (audio only);
