Original 1st printing 17&1/2 x 22&1/2" late-1966 "oddball" (not for a specific event) poster, "the Joysday Machine";

Design by Michael Rossman (helped by Karen & Jan), medium thick vellum stock silkscreen poster is in good (B) condition; there is a moderate degree of toning/wear around the outer margin area, along with a couple of small diagonal corner-tip bends, a bit of curling to the paper, a bit of light surface wear (smudges/pin-prick stains), a couple of small tears along the left margin and a series of nearly-invisible soft horizontal roll creases, otherwise fine.

 Totally BIZARRE late-'66 psychedelic poster, I think this one comes from Berkeley.
