I can't help but remembering from On A Pale Horse (Incarnations of Immortality):
What followed was a life-size billboard painting of a truly statuesque young woman in the process of disrobing. In the corner were the two little red devil trademark figures. Dee & Dee, male and female, complete with cute miniature pitchforks- The male was peeking up under the model’s skirt and remarking in small print, “You can’t touch that in Heaven!” Then came the final sign, the signature, HELLFIRE, written in lifelike flames.
