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 BEAUTIFUL near mint (A-) condition; aside from a couple of nearly-invisible handling/edge dings, one or two tiny surface scrapes and a tiny bit of pen scratch on the reverse, this example looks just about as bright/clean as the day it rolled off the press.

 Very sharp late-1970 Bill Graham Presents poster from Berkeley.
