Original 1st printing* (see below) 16&5/8 x 21&1/2" concert poster for Big Brother and the Holding Company (featuring Janis Joplin) appearing with Electric Flag and Sweetwater at the Earl Warren Showgrounds in Santa Barbara, CA on 2/3/1968.

 Art by Frank Bettencourt, medium-thin flat vellum stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a tiny pressure crease/bump in the top right corner tip and a few soft handling dings scattered throughout the image/margin area, it is a VERY sharp example of the semi-uncommon first printing of this early-'68 Big Brother poster from Southern California.

*the first printing, in addition to being on a more porous vellum stock (reprints are on a smoother index), has a pair of minor stripping flaws, where the "l" of "Earl" and "W" of "Warren" are overprinted slightly into the blue field at the bottom of the poster (this same error is mirrored on the original tickets for the show and was corrected on subsequent printings)
