Original 1st printing 22 x 14" concert poster for James Cotton appearing with Big Brother (featuring Kathy McDonald) at Earth in San Diego, CA from 11/5-6/1971.

 Artist unknown/not credited medium-thick flat index stock poster is in used (B-) condition; there are large fossilized tape marks with a couple of small surface pulls in all four corners (and on the reverse side, along with a couple of additional surface pulls), plus a fair amount of edge wear/creasing (numerous small tears/creases, glue residue spots), a bit of mild paper toning, a series of semi-camouflaged thin vertical stress bends and tiny pin-prick age spots hiding within the image area, soft/creased corner tips... definitely a bit on the worn/used side, but still pretty cool (and uncommon).
