An original 1968 Concert Poster for the Mothers of Invention at the Berkeley Community Center. This is the only example of this classic we've ever seen. Featuring psychedelic design and a great double photo of Frank Zappa, this poster measures 17" x 11" and is printed on card stock. In excellent condition, with very light overall toning, pinholes in top corners, tape pulls and some light water spots on back–invisible from the front.
