If proof was ever needed that Frederic Wertham was right, here it is. Comics do seduce the innocent. The problem is that this ad was published in 1967, years after the Comic Code was introduced, showing that the truly subversive will always slip under the radar.

Wertham, if you didn't know, wrote the book "Seduction of the Innocent". Published in 1954, it led to the Comics Code, which in turn killed the thriving horror and crime comics of the 1950s and tamed comic books until the code was eventually superseded in the late 1990s.

Zappa in many ways was the original pop-culture subversive and this ad proves it all. It's worth looking at the large version just to read all of the text. Aside from merely the title (which you'd think says it all), look for highlights like: "Cleans you! Thrills you! Cleans and thrills you! Fun. Expensive"
