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 very good to excellent (B/B+ to B+) condition; there are a couple of soft roll bends along the top and upper right margins, along with a 1" diagonal bend and a soft rub mark/scuff in the lower right corner tip and a few stray handling/stress creases here and there, otherwise it is a VERY nice-looking example of this charming original 1967 Bay-Area benefit poster with a sweet design and a killer lineup.
