Stanley George Miller (1940 - ), also known as Mouse or Stanley Mouse, is an American artist who is best known for his 1960s psychedelic rock poster designs and album covers for the Grateful Dead, Journey, and other bands. This poster celebrates the 25th anniversary of San Francisco's first Human Be-In and the 4th Annual Digital Be-In. The Human Be-In was an event held in San Francisco's Golden Gate Park Polo Fields on January 14, 1967. It was a prelude to San Francisco's Summer of Love, which made the Haight-Ashbury district a symbol of American counterculture and introduced the word "psychedelic" to suburbia.
