Original 1st printing (West Coast Litho credit) 14 x 21&7/8" concert poster for the Grateful Dead appearing with Tim Rose and Big Mama Mae Thornton at the Fillmore Auditorium in San Francisco, CA from 12/9-11/1966.
Art by Wes Wilson, image is # 41 in the Bill Graham/Fillmore series.
Medium flat index stock poster is in absolutely fantastic mint/near mint to near mint (A/A- to A-) condition; just the slightest trace of surface wear and a tiny stray handling ding or two, otherwise it is pretty much as sharp/crisp an example as you can hope to find.
KILLER 1st printing late-'66 Dead poster from the Fillmore in GORGEOUS condition.
