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 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 semi-pronounced 5" diagonal bend in the upper left margin/corner, along with a 1" tear in the right margin (just to the right of the second "d" in "Dead"), a few thin vertical stress creases in the top center margin, a small 1" bend in the top right corner tip, a tiny bend in the lower right corner, a soft pinch crease on the "la" of "Airplane", a bit of blue ink spread in a couple of places and a stray pinch ding/fingerprint/thin surface scratch or two hiding within the image area, otherwise fine.
 
 FANTASTIC-looking 1st printing example of this killer '69 JA/GD image from the Bill Graham series.
