Original 1st printing 14&1/2 x 22&1/2" concert poster for Spirit appearing with Michael Finnigan at Earth in San Diego, CA from 9/10-11/1971.

 Art by Glenn Chase, medium-thick flat index stock poster is in decent/used (B/B- to B-) condition; there are large fossilized/browned tape marks/pulls in all four corners, along with a decent amount of edge creasing along the lower left margin, creasing/wear in all four corners, light paper toning, a few stray bends/creases, pin-prick spots and tiny scuffs scattered throughout the image area, a semi-flattened horizontal center crease, tape pulls on the reverse and a few other minor issues... definitely a well-worn example, but I have never seen another one- VERY obscure early-'70's concert artifact from a fairly small Pacific Beach nightclub/venue.
