Original 1st printing 13&1/2 x 18&1/8" event/concert poster for the 3/31/1967 "Fluxfest", held at Longshoreman's Hall in San Francisco, CA. 

 Poster lists performances/appearances by Quicksilver Messenger Service, the Wildflower, the San Francisco Mime Troupe and more.

Art by (and SIGNED in black pen by) Ida Griffin, medium flat index stock poster is in excellent to near mint (B+) condition; just a light amount of light handling wear, a few stray surface/edge dings and that's it... a very sharp-looking ARTIST-SIGNED example of this semi-obscure 1967 SF event poster.
