Chicano art movement: The Chicano Art Movement represents attempts by Mexican-American artists to establish a unique artistic identity in the United States.  Much of the art and the artists creating Chicano Art were heavily influenced by Chicano Movement (El Movimiento) which began in the 1960s.  Chicano art was influenced by post-Mexican Revolution ideologies, pre-Columbian art, European painting techniques and Mexican-American social, political and cultural issues.  The movement worked to resist and challenge dominant social norms and stereotypes for cultural autonomy and self-determination.  Some issues the movement focused on were awareness of collective history and culture, restoration of land grants, and equal opportunity for social mobility.  Throughout the movement and beyond, Chicanos have used art to express their cultural values, as protest or for aesthetic value.  The art has evolved over time to not only illustrate current struggles and social issues, but also to continue to inform Chicano youth and unify around their culture and histories.  Chicano art is not just Mexican-American artwork: it is a public forum that emphasizes otherwise "invisible" histories and people is a unique form of American art.

Fear and Loathing in Las Vegas: Fear and Loathing in Las Vegas: A Savage Journey to the Heart of the American Dream is a novel by Hunter S. Thompson, illustrated by Ralph Steadman.  The book is a roman à clef, rooted in autobiographical incidents.  The story follows its protagonist, Raoul Duke, and his attorney, Dr. Gonzo, as they descend on Las Vegas to chase the American Dream through a drug-induced haze, all the while ruminating on the failure of the 1960s countercultural movement.  The work is Thompson's most famous book, and is noted for its lurid descriptions of illegal drug use and its early retrospective on the culture of the 1960s.  Its popularization of Thompson's highly subjective blend of fact and fiction has become known as gonzo journalism.  The novel first appeared as a two-part series in "Rolling Stone" magazine in 1971, was published as a book in 1972.  It was later adapted into a film of the same name in 1998 by Terry Gilliam, starring Johnny Depp and Benicio del Toro who portrayed Raoul Duke and Dr. Gonzo, respectively.
