There have been music discussion comments through the years on whether the Pet Sounds sleeve picture is bad.
“Is the Pet Sounds studio album cover truly the worst ever by a major band or act?” is still on another forum.
The only Blind Faith album had a naked girl and then had to be recalled from all stores and replaced with a mundane photo of the group (Clapton,Winwood,Ginger Baker,Rick Grech) Eric Clapton later said the girl was not actually underage, just small breasted and young appearing. And that he had no way whatsoever in the choice of album sleeves, nor did his bandmates. Company lost money in the recall.
Black Sabbath’s “Sabotage” album cover is considered to be really bad. I don’t know what they were trying to accomplish with that cover.
