Original 1st printing 13&7/8 x 21&1/8" (top/bottom edges trimmed by approximately 1/8" on each side) concert poster for Quicksilver Messenger Service appearing with Don Ellis and Rockwell at the Fillmore West in San Francisco, CA from 6/18-21/1970.

 Art by David Singer, image is # 239 in the Bill Graham/Fillmore series. 

 Medium glossy-coated index stock poster is in used (B-) condition; beyond the edge trimming, there is a moderate amount of surface scuffing throughout the poster, along with multiple pin holes in all four corners, a bit of diagonal creasing in the lower left corner, a couple of what look like black marker scratches between the "c" and "k" of "Quicksilver" and other assorted minor issues... definitely a survivor, but still a nifty artifact.
