In the past, many album covers have been banned for explicit images. What you may not know however, is that there are two albums that weren't released because their covers depicted unsanitary toilets.
Below, If You Can Believe Your Eyes And Ears by The Mama's and the Papa's, was instead released with a scroll over the image of a toilet (left).
The Rolling Stones' album, Beggars Banquet, featuring the song "Street Fighting Man" was banned for its cover, featuring a run down toilet in an unclean bathroom scene (left). The album art was replaced by the image on the right.
