include artists choosing to put a photo of themselves, which is one of the factors that add to the observation of the band, the musician, and the music. The album cover eventually became an important part of the culture of music. Under the influence of designers like Bob Cato, who at various stages in his long music career was vice president of creative services at both Columbia Records and United Artists, album covers became renowned for being a marketing tool and an expression of artistic intent. Album art has also been discussed as an important postwar cultural expression. During the early 1960s, the Beatles' With the Beatles, Bob Dylan's The Times They Are a-Changin' and the Rolling Stones' self-titled debut album each contained a cover photograph designed to further the musical artist's public image. Author Peter Doggett also highlights the cover of Otis Redding's Otis Blue, containing a photo of a young white woman, as a design that "played a dual role: she represented the transcendent power of the music, and obscured the race of its creator." The standard portrait-based LP cover was further challenged over 1965–66 by Dylan's Bringing It All Back Home, through the inclusion of symbolic artefacts around the singer; the artificially stretched faces of the Beatles shown on their Rubber Soul album; and the darkened hues applied to the Rolling Stones on Aftermath. Gatefold covers (a folded double cover) and inserts, often with lyric sheets, made the album cover a desirable work in its own right. Notable examples are the Beatles' Sgt. Pepper's Lonely Hearts Club Band, which had cut-out inserts, printed lyrics, and a gatefold sleeve, even though it was a single album; the Rolling Stones' Exile on Main Street, which had a gatefold and a series of 12 perforated postcards as inserts (taken by photographer Norman Seeff); and Pink Floyd's The Dark Side of the Moon, which had a gatefold, lyrics, no title on the sleeve, and poster and sticker inserts. The Band's 1970 release Stage Fright, which included a photograph by Seeff as a poster insert, is an early example of LP artwork quickly becoming a collector's item. The move to the small (less than 1/4 the size of a record) CD format lost that impact, although attempts have been made to create a more desirable packaging for the CD format, for example the reissue of Sgt. Pepper, which had a cardboard box
