Original 1st printing 4&1/4 x 5&3/4" event handbill for the Central Park Easter Be-In, held in Sheep's Meadow (CP) in New York City on 3/26/1967.

 Art by Peter Max , thin vellum stock handbill (*red/green version) is in near mint (A-) condition; aside from ta couple of very well-camouflaged minuscule pinch dings (mostly visible on the reverse side), it is a GORGEOUS example of this early NYC hippie event artifact.
