Original 1st printing 15&7/8 x 19&7/8" concert poster for Quicksilver Messenger Service appearing with Gideon & Power at Earth in San Diego, CA from 8/20-21/1971.

 Art by Glenn Chase, medium-thick flat index stock poster is in good to decent (B to B/B-) condition; there is a semi-pronounced horizontal center crease, along with a 2" diagonal bend in the upper left corner, a 3" diagonal bend in the lower left corner, a 4-5" diagonal bend in the lower right margin/corner, a bit of tattering/wear and a few tiny pin-prick mold spots along the right margin, a bit of light surface wear, a few stray thin bends and light handling creases here and there, large tape pulls on the reverse and a bit of mild paper toning... definitely a bit worn, but still a SUPER-obscure early-'70's Quicksilver concert artifact from a small Pacific Beach nightclub/venue.
