From Beyond the Perf:
The stamp features a photograph taken by Frank Bez during the photo session for Ring of Fire: The Best of Johnny Cash (1963). In the photo, Cash stares out at the viewer through a veil of shadow, his brooding expression fitting for an artist known to so many people simply as “the Man in Black.” The stamp sheet evokes the appearance of a vintage 45 rpm record sleeve. One side of the sheet includes the stamps and the image of a sliver of a record seeming to peek out the top of the sleeve. A larger version of the photograph featured on the stamp and the logo for the Music Icons series appear on the reverse side.
