This unauthorized biography of the Doctor is a great one. the chapers are seperated into time frames of Hunter's life (louisville, south america, what he was doing in the 70's, etc), and are filled mostly with antecdotes, quotes from people who knew him, and various backround information.
there are three picture sections in the book- 1st from when he was in his 20's, second is a Ralph Steadman's pictures of Hunter gallery, the third is random pictures of Hunter from the 70's through the 90's.
I recommend the book highly to every Hunter Thompson fan, especially if you like reading about his exploits as much as i do.
(this book is 200/5 stars, btw)
