Some of the most famous albums in history use conceptually strong cover art with no trace of the album's title or even the band name on the front sleeve. The idea was to make the cover stand out so much in record stores so much that potential buyers pick it up because of the image alone. It usually worked, and some of the best known albums of the late 1960s/early 1970s, like Blind Faith, King Crimson or Pink Floyd, used this approach.
