Original 1st printing 14 x 20" concert poster for Quicksilver Messenger Service appearing with Ace of Cups and Congress of Wonders at the Sound Factory in Sacramento, CA on 8/9-10/1968.
Design by San Andreas Fault (Tad Hunter), medium-thick glossy-coated index stock poster is in very good to excellent (B/B+ to B+) condition; the main issue on this example(and others from this part of the print run) is a bit of light ink streaking/surface scuffing on the red and black passes of ink, plus a few ultra-light surface scratches and a few stray fingerprints here and there- otherwise it is in really clean shape- no tears/stains/bends, etc... physically fine.
Very cool-looking mid-'68 Quicksilver concert poster from the short-lived Sacramento psychedelic ballroom. For a brief background on the Sound Factory, read HERE;
