Original 1st printing 13&3/4 x 19&3/4" concert poster for the 30th Anniversary of the Summer of Love concert, held at Beach Chalet Meadows in Golden Gate Park in San Francisco, CA on 10/12/1997.
 Art by (and SIGNED and numbered 495/1000 in black flair pen by) Dennis Loren (produced by Chet Helms of the Family Dog), the event featured performances by Jefferson Starship, Sons of Champlin, the Charlatans, Country Joe McDonald and numerous all-star jams featuring members of Moby Grape, Santana, Grateful Dead, Steve Miller Band, Quicksilver Messenger Service, along with Ken Kesey and the Merry Pranksters, Michael McClure/Ray Manzarek (the Doors) and MANY more. 
 
Medium-thick glossy coated index stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a touch of handling wear and a series of VERY light thin surface scratches in the upper right quadrant, it is a great-looking ARTIST-SIGNED example of this colorful poster from this fondly-remembered event.
