Original 1st printing 13&1/2 x 21" concert poster for Country Joe & the Fish appearing with the Hourglass (featuring Duane and Gregg Allman of the Allman Brothers Band) and the United States of America on 5/3/1968 and Moby Grape appearing with the Hourglass and U.S.A. on 5/2 & 5/4/1968, all shows held at the Fillmore Auditorium in San Francisco, CA.
Art by Mari Tepper, image is # 118 in the Bill Graham/Fillmore series.
Medium-thick flat index stock poster is in near mint (A-/B+) condition; just a small thin horizontal roll bend along the lower right margin, a soft pinch bend or two hiding within the image area and a pair of soft mounting tape pulls on the reverse top margin, otherwise it is a nearly-UNBEATABLE example of this VERY strange-looking 1968 Fillmore poster.
