Original 1st printing 14 x 20&1/8" concert poster for rock n' roll pioneer Bo Diddley appearing with Lee Michaels at the Avalon Ballroom in San Francisco, CA from 11/17-19/1967.
Art by William Henry, image is # 92 in the Family Dog/Avalon series.
Medium flat index stock poster is in absolutely fantastic mint/near mint to near mint (A/A- to A-) condition; just a tiny bend in the upper right corner tip, a whisper of edge toning and a stray edge ding or two, otherwise it is an IMMACULATE example of this original late-'67 poster from the Avalon.
