Rick Griffin's famous flying eyeball poster is considered by many to be the single finest example of San Francisco psychedelic poster art. The image comes from this fabulous motherlode of eye candy that is Paul Olsen's Fillmore and Avalon poster collection
. It is the largest and most complete collection of its sort. He would like to sell it as a whole--The Whitney Museum wants to buy it but can't afford it. That should tell you something. Come step behind the Indian bedspread curtain and smell the incense.
