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  Lee Conklin, image is # 121 in the Bill Graham/Fillmore series.

 Medium-thick flat index stock poster is in near mint (A-) condition; aside from a TINY bump/bend in the lower left corner tip, it is a nearly-perfect example of this very weird-looking Lee Conklin Fillmore poster from mid-'68.
