Original 1st printing (blue background, no "W") 14&1/8 x 21" concert poster for Jefferson Airplane and the Grateful Dead appearing with Mongo Santamaria at Winterland on 5/2-3/1969 and Mongo Santamaria headlining over Cold Blood and the Elvin Bishop Group at the Fillmore West (all in San Francisco, CA) on 5/1 & 5/4/1969.
Art by Randy Tuten, image is # 171 in the Bill Graham/Fillmore series.
Medium glossy-coated index stock poster is in GORGEOUS near mint (A-) condition; just an ultra-tiny corner bump in the bottom left corner tip and a stray fingerprint or two, otherwise fine.
A REALLY sweet-looking 1st printing example of this classic '69 JA/GD image from the Bill Graham series. Check out the 5/3 show HERE:
