Original 1st printing 14 x 21" concert poster for Iron Butterfly with the James Cotton Blues Band and A.B. Skhy at the Fillmore West in San Francisco, CA on 1/23-26/1969. Art by Lee Conklin, image is number 157 in the Bill Graham/Fillmore series. Medium glossy coated index stock poster is in beautiful near mint (A- to A-/B+) condition; a couple of tiny edge dings in the right margin, a stray fingerprint or two and a miniscule bend in the upper right corner, otherwise fine. One of Lee's stranger Fillmore images, this one has really vibrant/bright colors and a heavily psychedelic design.
