If you're a fan or a collector of art from the 60s and 70s, you will enjoy selecting one of our psychedelic posters. The term psychedelic comes from the ancient Greek language. Psyche means soul and deloun translates to mean visible or revealing. The art form was born out of hallucinations and visualizations which often were attributed to using mind-altering drugs. The result includes brightly-colored fractals, paisley patterns, spirals or repeating motifs.
