Original 1st printing 13&7/8 x 24&3/4" concert poster for Bola Sete appearing with Buffalo Springfield (featuring Neil Young and Stephen Stills) and Country Joe & the Fish at the Fillmore Auditorium in San Francisco, CA from 11/11-13/1966.
Art by Wes Wilson, image is # 36 in the Bill Graham/Fillmore series.
Medium flat vellum stock poster is in used (B-) condition; there is a fairly decent amount of edge wear along the top/bottom margins (several tears, hard creases, a small chunk of paper out of the lower left corner tip), along with a large 4-5" diagonal bend in the upper left corner, a series of small pin-prick splatter marks scattered around the lower portion of the image area, a large 2" vertical tear in the top center margin, a few light handling/stress creases, staple/pin holes in the corners, a bit of pencil scratch on the reverse... you get the idea, this one was very likely pulled down from public display at the time of the shows.
Conditional issues aside, this example is still not without its charms and is definitely priced to move.
