The late, iconic music photographer Jim Marshall captured much of the Grateful Dead's career and life. He took over 10,000 photos of the Grateful Dead. Hundreds of those photos are featured in the book “The Grateful Dead by Jim Marshall.” It covers their formative years from 1966 to 1977. Photographer Amelia Davis is the co-author of the book. She was Jim Marshall’s personal assistant who preserved his work. Lifelong Deadhead and writer Dan Sullivan  contributed an essay to the book.
