Original 1st printing 14 x 21" concert poster for the Chambers Brothers appearing with It'a A Beautiful Day and Crazy World of Arthur Brown from 6/18-20/1968 and Quicksilver Messenger Service appearing with Sly & the Family Stone from 6/21-23/1968, all shows held at the Fillmore West in San Francisco, CA.

 Art by (and SIGNED in black pen by) Lee Conklin, image is # 125 in the Bill Graham/Fillmore series.

 Medium flat index stock poster is in absolutely fantastic mint/near mint to near mint (A/A- to A-) condition; a VERY sharp/crisp ARTIST-SIGNED example of this highly psychedelic Lee Conklin image from the Fillmore.

 LOTS of little intricate details/forms hiding within the lettering on this one.
