Original 1st printing 14 x 22&3/4" concert poster for "the Big "O", the one and only Otis Redding (and His Orchestra) appearing with the Grateful Dead, Johnny Talbot and De Thangs and Country Joe & the Fish at the Fillmore Auditorium in San Francisco, CA from 12/20-22/1966.
Art by Wes Wilson, image is # 43 in the Bill Graham/Fillmore series.
Medium flat index stock poster is in fantastic mint/near mint to near mint (A/A- to A-) condition; perhaps there's a stray surface/handling ding hiding somewhere, but basically it's just about as sharp as they come. This particular example has very strong inking... one of the darkest ones I've ever seen.
