Original 1st printing 17 x 11" event poster for the Yippie-sponsored Easter Blow-Out Conspire-In (Be-In) held in Central Park (Sheep's Meadow) in New York City on 4/6/1969.

Acts listed include: the Blues Project, Elephant's Memory, Children of God, Thunderhead and Charlie Brown (unknown who actually appeared- definitely NOT the Blues Project, who had broken up by the time of this event)

 Designer unknown/not credited, thin vellum stock poster is in excellent (B+) condition; there are a couple of tiny edge tears along the lower right margin with a thin crease running between them, along with a few light handling creases scattered along the top margin and a whisper of handling, otherwise it is a great-looking example of this VERY OBSCURE 1969 Yippie artifact from the last Central Park Be-In held in the '60's.

Apparently, this Be-In had a bit more of a radicalized/rowdy crowd than previous years, which probably explains why it was the last one.
