Original 1st printing 26&3/4 x 19&3/4" concert poster for Big Brother & the Holding Company (featuring Janis Joplin) appearing with Blue Cheer and Mint Tattoo at the Shrine Exposition Hall in Los Angeles, CA from 1/12-13/1968.
Art by Honeya and Casandra, image is from the Pinnacle/Shrine series.
Medium-thin flat index stock sheet is in BEAUTIFUL near mint (A-) condition; aside from a few VERY well-camouflaged handling dings hiding within the image area and a couple of tiny roll bends in the corner tips, it is an UNBEATABLE example of this semi-uncommon Pinnacle Shrine poster from early-'68.
