Original 1st printing 14&1/8 x 21" concert poster for "Dr. Sunday's Medicine Show", a benefit for the Haight-Ashbury Free Clinic, featuring Big Brother & the Holding Company (featuring Janis Joplin) appearing with Quicksilver Messenger Service, Freedom Highway, Mother Earth (with Tracy Nelson), Ace of Cups and Mad River at Family Park in San Jose, CA on 10/8/1967.
 
 Art by Mari Tepper, image is featured in the Art of Rock on page 232 (plate 2.339).
 
 Medium-thick flat index stock poster is in near mint to excellent (A-/B+ to B+) condition; there are a couple of ultra-soft well-hidden diagonal bends in the lower left/right corners along with a hint of handling wear and a few tiny pin-prick mold spots on the reverse-side bottom margin, otherwise it is a SUPERB example of this very sweet original 1967 1st printing Bay-Area benefit poster with a great design and a killer lineup.
