Original 1st printing 9&3/8 x 14" silkscreen event mini-poster for "The World's Largest Hayride to the Sixth Door", a multi-media presentation/"happening", held at Graceada Park in Modesto, CA on 5/20/1967. Designer unknown, event was sponsored by "Campus Life", a Christian-based youth organization. Designer unknown, medium-thick flat textured "construction paper" stock silkscreen poster is in excellent (B+) condition; a few stray surface scratches and tiny dings, a rough/hand-torn bottom edge and a couple of tiny soft bends along the top margin, otherwise fine. Totally weird psychedelic event poster from Modesto with a cool design... the text at the bottom explains it all;

"THE SIXTH DOOR... is a creative multi-media presentation of personal concern. The project is sponsored locally by Campus Life. Through the use of a battery of slide and movie projectors, lighting effects and a soundtrack of folk, rock and soul music, participants experience a world of despair.  Confronted with the frustration of doorways in life which offer no lasting happiness, they find yet another, the sixth door, which opens to the promise of a life that's new."
