Presented by The Chambers Project Gallery and PACT: Psychedelic Arts and Culture Trust

GRASS VALLEY, CA. The Psychedelic Arts and Culture Trust (PACT) celebrates the sixtieth anniversary of the Grateful Dead with 60 Years of the Grateful Dead, a landmark retrospective honoring the original art and imagery that shaped the band’s identity across six decades of music, culture and myth.

Curated by Brian Chambers, the exhibition gathers many of the original works created for the Dead’s most iconic posters and album covers. Featured artists include Rick Griffin, Stanley Mouse, Alton Kelley, Victor Moscoso, Wes Wilson, Bill Walker, Owsley “Bear” Stanley and others whose work helped define the psychedelic era.

Highlights include

Rick Griffin Originals
Historic illustrations, preliminary sketches, paintings and artifacts, including the original pen and ink Hawaiian Aoxomoxoa drawing considered one of the finest works of psychedelic typography, his acrylic circus paintings for Without a Net, the original Europe 90 tour poster and his first major work, the 1967 “Pow-Wow” Human Be-In poster.

Bill Walker’s Anthem of the Sun
A massive, vibrant mandala of color and rhythm created for the band’s second album. Walker continued refining the piece for decades after its use on the cover, capturing the spirit of the late sixties and the creative impact of LSD on art.

Historic Acid Test posters
Designed by Paul Foster and hand colored by Owsley “Bear” Stanley, including the first public use of the name “Grateful Dead” after the band’s early Warlocks era, and the only known signed copy of Bear’s 1966 Trouper’s Club poster.

A Original Skeleton Amidst Roses
Created by Victorian artist Edmund J. Sullivan in 1900 and later published in the 1913 edition of The Rubaiyat of Omar Khayyam, this original Skeleton Amidst Roses illustration was adapted by Mouse and Kelley for the Avalon Ballroom in 1966 and for the 1971 Skull and Roses album. This marks the first time the original drawing has been exhibited in a Grateful Dead show.

Pioneers and Modern Masters
Limited edition posters and original works by contemporary poster artists AJ Masthay and Zoltron, who carry forward the counterculture tradition.

Exclusive New Grateful Dead merch

A rock concert style merchandise booth will offer brand new, officially licensed and extremely limited edition Grateful Dead gear designed and curated by Zoltron, available exclusively during the exhibition.

60 Years of the Grateful Dead opens Saturday, December 6, 2025, two days after the anniversary of the band’s founding, and runs through June 1, 2026.
