Original 1st printing 14&1/8 x 21&1/8" concert poster for Canned Heat appearing with Gordon Lightfoot and Cold Blood at the Fillmore West in San Francisco, CA from 10/3-5/1968.

 Art by (and SIGNED in black pen by) Lee Conklin, image is # 139 in the Bill Graham/Fillmore series.

 Medium-thick flat index stock poster is in absolutely FANTASTIC near mint (A- to A-/B+) condition; aside from a thin horizontal hairline crease running along the lower left margin/edge and a stray pinch ding or two hiding within the image area, it is a SUPERB-looking SIGNED example of one of Lee's wildest Fillmore images.
