Original 1st printing 14&1/4 x 20&1/4" concert poster for Sandy Bull appearing with the Congress of Wonders, the Hobbits and Bill Ham's Light Sound Dimension (L.S.D.) at the Western Front in San Francisco, CA from 7/7-8/1967. 

 

 Art by Greg Irons, medium-thin flat index stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a touch of toning, a couple of ULTRA-tiny edge dings scattered around the outer margin area and a couple of tiny surface smudges, it is a SUPERB-looking example of this oddball mid-'67 San Francisco poster with a great Greg Irons design ("Smedly One-Man Steam Band").
