Original 1st printing 11 x 17&1/2" concert poster for Purple Earthquake appearing with Lincoln's Promise and the Drongos at Jefferson Auditorium in Berkeley, CA  on 6/9/1967.

 Art by "R.D.", medium-thin flat index stock poster is in very good to excellent (B/B+ to B+) condition; there is a 1/2" tear in the upper right margin, a bit of creasing/wear along the top margin, a few light pin-prick surface stains hiding within the image area, a bit of light handling wear, a tiny bit of pencil scratch ('67) in the bottom right corner tip and on the reverse (1967), otherwise fine.

 Really neat-looking mid-'67 concert poster from an obscure Berkeley venue.
