Original 1st printing 11&1/2 x 16&1/4" concert poster for Initial Shock appearing with Salloom Sinclair and Mama Bear at the Sound Factory in Sacramento, CA from 12/20-21/1968. 

 Art by J.L. Pennington, medium glossy-coated index stock poster is in good/decent (B to B/B-) condition; there are multiple pin/staple holes in all four corners, along with a moderate amount of surface staining, a semi-soft 6" diagonal bend in the upper right corner and a series of fairly well-hidden scratches along the right side of the poster, otherwise OK... either way, not an easy find- even with the conditional issues.
