Original 1st printing 14 x 21&1/8" concert poster for the Yardbirds (featuring Jimmy Page) appearing with avant-jazz pianist Cecil Taylor and It's A Beautiful Day at the Fillmore Auditorium in San Francisco, CA from 5/23-25/1968. 

 Art by (and SIGNED in silver pen by) Lee Conklin, image is # 121 in the Bill Graham/Fillmore series.

 Medium-thick flat index stock poster is in VERY sharp near mint (A- to A-/B+) condition; aside from a series of tiny randomly placed pinch/stress bends hiding within the image area, it is a VERY sharp-looking ARTIST-SIGNED example of this ultra-psychedelic Lee Conklin Fillmore image.
