Original 1st printing 17&1/2 x 11&1/2" concert poster for Big Brother & the Holding Company (featuring Janis Joplin), appearing at Freeborn Hall on the campus of the University of California in Davis, CA on 5/17/1968.
Designer unknown/not credited, image is featured in the Art of Rock book on page 259 (plate 3.11).
Medium-thick smooth index stock poster is in STUNNING near mint (A-) condition; aside from a small pressure bend/crease in the bottom right corner tip and a tiny pen scratch on the reverse ("1968" in blue ballpoint), this example looks just as bright/sharp as the day it rolled off the press.
VERY COOL-looking (and HIGHLY uncommon) low-run regional Big Brother/Janis poster from the AOR.
