Original 1st printing 13&5/8 x 22" concert poster for the Otis Rush Chicago Blues Band appearing with the Grateful Dead and Canned Heat (Blues Band) at the Fillmore Auditorium in San Francisco, CA from 2/24-26/1967.

 Art by Wes Wilson, image is # 51 in the Bill Graham/Fillmore series (BG 51-OP-1 in the Eric King guide) 

 Medium flat vellum stock poster is in good to very good (B to B/B+) condition; there is a bit of fairly well-camouflaged stress creasing throughout the poster, along with thin hairline diagonal bends in all four corners, a soft/rounded bottom left corner-tip, a few tiny edge tears scattered along the left/right margins, a bit of light surface smudging on the "m" of "Fillmore", a whisper of edge toning in the upper left corner/margin and a few stray handling dings here and there, otherwise OK.

 Unlike a LOT of 1st printing examples currently in circulation, the colors on this one are still intact- none of the trademark ink fading/toning that often plagues the originals.
