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 on 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 (A/A- to A-) condition; there's only a stray handling ding or two around the outer edges and a tiny surface smudge or two, otherwise it's just as sharp/crisp an example as you hope to find anywhere. Check out this very interesting blog post regarding the back story of these shows and their significance to the Dead's late '66 musical output;
