Victor Moscoso was among the most gifted and influential artists to emerge from the Sixties counterculture, pioneering not only the psychedelic concert poster designs made famous during San Francisco's Summer of Love but also making his mark in underground comix. Born in Spain and raised in Brooklyn, Moscoso attended Cooper Union Art School before studying at the Yale School of Art; he arrived on the west coast in 1959 to enroll at the San Francisco Art Institute, and after graduation remained at the school for another five years to teach lithography. Alongside Rick Griffin, Wes Wilson, Stanley Mouse and Alton Kelley -- with whom his work was celebrated during the famed 1967 "Joint Show" -- Moscoso became one of the most famous of the psychedelic artists to surface during the mid-1960s, his provocative work for the Family Dog's dances at the Avalon Ballroom as well as his Neon Rose posters for the Matrix earning international attention. By 1968, he had turned his focus to underground comix storytelling, becoming one of the contributors to Robert Crumb's infamous Zap series; he also gained renown for his cover art for performers like Jerry Garcia, Bob Weir, Herbie Hancock and David Grisman. Moscoso additionally designed countless t-shirts and billboards, later winning a pair of CLIO awards for his animated advertising projects; he also worked in music video.
