Original 1st printing 13&5/8 x 22" concert poster for the Grateful Dead appearing with Otis Rush & His Chicago Blues Band and Canned Heat 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.
Medium-thick flat vellum stock poster is is VERY sharp near mint (A-/B+) condition; there is a tiny thin 3/4" diagonal crease in the top left corner tip, an almost-invisible trace of subtle smudging in the upper left corner, one or two stray edge dings and a pin-prick surface spot or two hiding within the image area, otherwise it is pretty much as crisp as they come.
This example exhibits none of the common ink fading issues that traditionally plague this poster, the colors are REALLY strong. An absolutely BEAUTIFUL specimen of the 1st printing BG 51 poster.
