Leading proponents of the 1960s psychedelic art movement were San Francisco poster artists such as: Rick Griffin, Victor Moscoso, Bonnie MacLean, Stanley Mouse & Alton Kelley, and Wes Wilson. Their psychedelic rock concert posters were inspired by Art Nouveau, Victoriana, Dada, and Pop Art. Richly saturated colors in glaring contrast, elaborately ornate lettering, strongly symmetrical composition, collage elements, rubber-like distortions, and bizarre iconography are all earmarks of the San Francisco psychedelic poster art style. The style flourished from about 1966 to 1972. Their work was immediately influential to vinyl record album cover art, and indeed all of the aforementioned artists also created album covers.
Although San Francisco remained the hub of psychedelic art into the early 1970s, the style also developed internationally: British artist Bridget Riley became famous for her op-art paintings of psychedelic patterns creating optical illusions. Mati Klarwein created psychedelic masterpieces for Miles Davis' Jazz-Rock fusion albums, and also for Carlos Santana Latin Rock. Pink Floyd worked extensively with London-based designers, Hipgnosis to create graphics to support the concepts in their albums. Willem de Ridder created cover art for Van Morrison. Los Angeles area artists such as John Van Hamersveld, Warren Dayton and Art Bevacqua and New York artists Peter Max and Milton Glaser all produced posters for concerts or social commentary (such as the anti-war movement) that were highly collected during this time. Life Magazine's cover and lead article for the September 1, 1967 issue at the height of the Summer of Love focused on the explosion of psychedelic art on posters and the artists as leaders in the hippie counterculture community.
