I call this the quintessential Bill Graham / Fillmore Auditorium concert poster… the Jefferson Airplane and Grateful Dead together, for two dates in the summer of 1966, with a classic poster design by Wes Wilson. This was the first Bill Graham psychedelic concert poster to used photographs of the musicians, and Wilson’s rolling, psychedelic lettering remains timeless. Enthusiastically discussed by collector Pete Howard of PosterCentral.com (phone 805-540-0020, email pete@postercentral.com).
