The world's premier dealer in the psychedelic poster art and rock music posters that promoted the 1960s & 70s concerts of legendary bands and performers at venues that included The Fillmore Auditorium, the Avalon Ballroom, and the Grande Ballroom.

Poster artists were inspired by the music. Bands like Jefferson Airplane, the Grateful Dead, Quicksilver Messenger Service—and performers like Janis and Jimi—set the bar high; add to that the purple haze of counterculture, acid tests, movement politics, war and peace, a gathering of tribes, a man on the moon. That was the palette from which psychedelic poster art emerged to shape popular culture.
