Original 1st printing (slate-blue background, no "W") 14&1/8 x 21" concert poster for Jefferson Airplane and the Grateful Dead appearing with Mongo Santamaria at Winterland from 5/2-3/1969, plus Mongo Santamaria headlining over Cold Blood and the Elvin Bishop Group at the Fillmore West on 5/1 & 5/4/1969. (*all shows held in San Francisco)
 
 Art by (and SIGNED in black sharpie by) Randy Tuten, image is # 171 in the Bill Graham/Fillmore series.
 
 Medium glossy-coated index stock poster is in very good (B/B+) condition; there is a bit of hard diagonal pressure creasing in the lower left corner (about a 2" square area), along with a tiny bend/pressure crease in the lower right corner tip, a few light thin surface scratches/light fingerprint smudges here and there and a soft pinch bend/pin-prick indentation or two hiding within the image area, otherwise fine.
 
 VERY nice-looking ARTIST-SIGNED 1st printing example of this classic '69 JA/GD image from the Bill Graham series.
