Original 1st printing 11 x 17&1/2" concert poster for Spirit appearing with the Elvin Bishop Group and Sha-Na-Na at the Boston Tea Party (15 Lansdowne Street location) in Boston, MA from 10/9-11/1969.

 Art by Eric Engstrom, medium-thick flat index stock poster is in good/decent (B/B-) condition; there is a 2" horizontal tear (sealed on the reverse with clear tape) in the left center margin, along with tiny pin holes in the upper left/right and bottom left corner tips, in the bottom center margin and in the left center margin, a light amount of surface dirt/toning with a couple of tiny scuff marks here and there, a few tiny stress/handling creases lurking within the image area and a set of very ight tape pulls on the reverse side, otherwise OK.

 Conditional issues aside, it is still a very presentable example of a fairly uncommon late-'69 Tea Party poster.
