The concept of Psychedelic Art is that the state of consciousness produced by psychedelic drugs changes the source of artistic inspiration. Psychedelic Art refers to the psychedelic experience and illusion caused by ingestion (such as LSD and naked mushroom element), or the artistic, graphic or visual display related to or inspired by it.
The term "psychedelic" (coined by Humphrey Osmond, a British psychologist) means "the manifestation of the mind". According to this definition, all art depicting the inner world of the mind can be regarded as "psychedelic". The trippy tattoo I collected today is the perfect embodiment of Psychedelic Art in tattoo art.
The main supporters of the Psychedelic Art Movement in the 1960s were poster artists in San Francisco, such as Rick Griffin, Victor Moscoso, Bonnie MacLean, Stanley Mouse & Alton Kelley and Wes Wilson. This style flourished between 1966 and 1972. Their works immediately had an impact on the cover art of vinyl records.
