In a response to why only one copy of "The Mark Of The Beast" was pressed, Mr. Doctor quoted "This is a painting, not a graphic work."

Mr. Doctor is the enigmatic and mysterious leader of and creative drive behind Devil Doll. He is extremely secretive about his identity, to protect his privacy. It is known that he is Italian, however, and he supposedly lives in Ljubljana. Since 1992, after being heavily censored in the introduction of a television showing of Sacrilegium, Mr. Doctor has refused to give interviews.
