The Beatles - The Beatles (1968) aka The White Album
The album's sleeve was designed by Richard Hamilton, a notable pop artist who had organised a Marcel Duchamp retrospective at the Tate Gallery the previous year. Hamilton's design was in stark contrast to Peter Blake's vivid cover art for Sgt. Pepper's Lonely Hearts Club Band, and consisted of a plain white sleeve. The band's name was discreetly embossed slightly below the middle of the album's right side, and the cover also featured a unique stamped serial number, "to create," in Hamilton's words, "the ironic situation of a numbered edition of something like five million copies."
Indeed, the artist intended the cover to resemble the "look" of conceptual art, an emerging movement in contemporary art at the time. Later vinyl record releases in the US showed the title in grey printed (rather than embossed) letters. Early copies on compact disc were also numbered. Later CD releases rendered the album's title in black or grey.
