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 flat vellum stock poster is in VERY crisp/sharp near mint (A-) condition; to be honest, I can't really see any visible flaws on this one, but there could be a hairline pinch bend or pin-prick ink spot hiding somewhere if you really put it under the microscope... either way, this is just about as clean/un-touched an example as you can hope to find and definitely among the finest I have seen in almost 25 years. BEAUTIFUL specimen.
