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 flat index stock poster is in excellent (B+) condition; only a tiny soft stain/discoloration in the extreme top right corner margin, a couple of nearly-invisible horizontal/diagonal/curved bends in the right margin and the slightest amount of handling/surface wear, otherwise fine.

 Real sharp-looking Fillmore-era Bill Graham Presents "marquee style" poster from Berkeley.
