GRATEFUL DEAD Original Fillmore Auditorium Poster from October 1966

A funky psychedelic but in a black and white way - GRATEFUL DEAD Original Fillmore Auditorium Poster from October 21 & 22, 1966. The opening act of Lightnin' Hopkins whom the Rolling Stone magazine ranked number 71 on its list of the 100 greatest guitarists of all time must have made this one incredible show. Early Dead and the now the long dead, together for one show. I have the poster to prove it.
