Original 1st printing 13&3/4 x 21" concert poster for ex-Lovin' Spoonful leader John Sebastian appearing with Poco on 4/12/1970 and Frank Zappa (and the Hot Rats) appearing with Boz Scaggs on 4/19/1970, both shows promoted by Bill Graham Presents and held at the Berkeley Community Theatre in Berkeley, CA.

 Medium-thick semi-gloss coated index stock poster is in very good (B/B+) condition; there is a bit of horizontal creasing, a couple of tiny tears and  a few light smudges along the top border, along with a few stray pin-prick surface spots scattered around the image area/outer margins, a light amount of toning and a few stray handling dings here and there, otherwise fine.

 Very simple, but still cool late-1970 Bill Graham Presents poster from Berkeley.
