Original 1st printing 14&1/4 x 22&1/2" uncut printers proof concert poster (extra top/bottom margins) for the Paul Butterfield Blues Band appearing with the Hello People and Santana from 7/30-8/1/1968 and Canned Heat appearing with Initial Shock and Iron Butterfly from 8/2-4/1968, all shows held at the Fillmore West in San Francisco, CA.

 Art by (and SIGNED in black pen by) Lee Conklin, image is # 131 in the Bill Graham/Fillmore series.

 Medium-thick flat index stock poster is in absolutely GORGEOUS near mint (A-/B+) condition; only the slightest whisper of handling/surface wear (a couple of VERY well-hidden tiny creases/pinch dings and a nearly-invisible thin vertical drip stain on the left hand) and a couple of fingerprint smudges along the bottom border and left center margin (these are in the printing, and more than likely one of the reasons why this example was remaindered) and a couple of minor edge/corner dings, otherwise fine.

 VERY cool-looking ARTIST-SIGNED oddball Fillmore test proof from 1968.
