answer: Ralph Steadman
context: Title: Fear and Loathing in Las Vegas
  Passage: 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.

  Title: Gonzo: Photographs by Hunter S. Thompson
  Passage: GONZO: Photographs By Hunter S. Thompson is a limited-edition 224 page visual biography of photographs taken by, or of, Hunter S. Thompson, published in late 2006 by AMMO Books.  Thompson's snapshots were a combination of the subjects he was covering, stylized self-portraits, and artistic still life photos.  The "London Observer" called the photos "astonishingly good" and that "Thompson's pictures remind us, brilliantly in every sense, of very real people, real colours".  With an introduction by Johnny Depp (a friend of Thompson, and portrayer of his author surrogate, Raoul Duke, in "Fear and Loathing in Las Vegas"), the book stands as the only authorized biography of Hunter S. Thompson ever published.  Together with AMMO publisher Steve Crist, Thompson was deeply involved in the book's creation in the final months of his life, and it was the author's final work in progress when he committed suicide in February 2005.
