Original 1st printing 21&1/4 x 16&3/8" concert poster for John Lee Hooker appearing with Mother Earth (featuring Tracy Nelson) and Loading Zone at the Carousel Ballroom in San Francisco, CA from 4/4-6/1968.
Art by Lenny, medium flat index stock poster is in absolutely GORGEOUS near mint (A- to A-/B+) condition; with the exception of a tiny pin-prick surface stain/light handling ding or two and a bit of light ballpoint pen scratch on the reverse ("Roberta"), this example can not be topped.
VERY weird/unusual Carousel poster with an eclectic blues-rock lineup. I don't know why this one didn't make it into the Art of Rock book... it's a pretty cool image.
