Original 1st printing 23 x 29" 1968 psychedelic promotional poster for Southern California (Pasadena) underground radio station KPPC-FM, featuring Big Brother & the Holding Company (with Janis Joplin).
 
 Artist unknown/not credited, medium-thick flat vellum stock poster is in good/decent (B to B/B-) condition; the left and right margins both have a moderate amount of creasing/wear with a small diagonal wedge missing from the upper right corner tip and a couple of tiny edge tears, tack holes in all four corners, a series of VERY light/thin stress bends scattered throughout the image area and a light amount of toning, otherwise fine.

 Neat-looking extra-large psychedelic Big Brother/Janis poster from a fairly short-lived underground radio station. Read more about KPPC HERE:
