Original 1st printing 7 x 10" concert/event handbill/flyer for "The E-vent", a party held at the Infinite Poster upstairs from the Cafe Au Go-Go in New York City's Greenwich Village on 4/28/1967. 

 Art by Gail Cochran/Liberty Graphics, performers listed include: the Mothers of Invention (with Frank Zappa), Dave Van Ronk and Ian & Sylvia, along with "chilled sangria, fresh spring fruits and nuts, posters and music"!

 Medium-thick flat vellum stock flyer is in BEAUTIFUL mint/near mint to near mint (A/A- to A-) condition; a VERY sharp/crisp example of this great-looking oddball early-'67 item from the Cafe Au Go-Go series, read more about the store and its influence HERE:
