Original 1st printing (blue background, no "W") 14 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 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 near mint to excellent (A-/B+ to B+) condition; just a touch of handling and a slight degree of toning along the bottom and right margins, otherwise a great-looking 1st printing example of this classic '69 JA/GD image.
