My mate Dave got me this for Christmas. It kinda covers a lot of the same territory as 'Walk The Line', childhood, start in music, up to Fulsom, and then jumps to the American Recordings sessions with Rick Rubin. It cuts between Cash's life, and Glen Sherley, an inmate of Fulsom who's desperate to meet Cash, and who sends him one of his songs, 'Greystone Chapel', which Cash performed at Fulsome and later recorded. It also incorporates some great wordless sequences depicting some of Cash's key tracks.
Very well-written, and the artwork is evocative, altogether making for a delightful and moving piece of work, and a splendid example of what the comic book medium is capable of.
