I often wonder how many artists ended up making explicit music simply to get that sticker. There's no doubt that it became a marketing ploy for artists. As an edgy teenager I was put off by albums that didn't have said sticker. What a time to be alive.

It is a great sticker: bold, all caps, tons of contrast. I think it would be really hard to fit more attention-gettingness in that little space.

Quite a lot. Frank Zappa had a ton of fun with it as well, putting his version of the notice on even his instrumental albums.
