Psychedelic posters of the late 1960s drew on bright colors, bold typography, and kaleidoscopic patterns that can be traced back to the movements of Art Nouveau, the Vienna Secession, and Surrealism.  The most influential designers working in the style were Alton Kelley, Victor Moscoso, Rick Griffin, Wes Wilson, and Stanley Mouse.
