Original 1st printing (West Coast Litho credit) 14 x 21&7/8" concert poster for the Grateful Dead 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; just the slightest trace of toning in the top right corner and a stray handling ding or two, otherwise it's as sharp/crisp an example as you can ask for. 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;
